The Meeting Between a Japanese Parliamentary Delegation and China’s International Liaison Department and the Structural Tensions in China-Japan Relations: Background, Implications, and Policy Recommendations

Executive Summary

Following Prime Minister Takaichi's remark about a "situation that threatens Japan's survival," a parliamentary delegation led by Shinichi Isa visited Beijing. However, the attempt to improve relations failed after Luo Gang, Deputy Head of the Chinese Communist Party's International Liaison Department, stipulated that Japan must revise its stance on Taiwan as a precondition for any change in China's policy toward Japan. The simultaneous use of a "neo-militarism" frame and rare earth export controls by both party and government channels suggests that Beijing has shifted from addressing the specific remark to challenging Japan's overall security policy. As China's comparative advantage in rare earth refining and processing is expected to persist for the next three to five years, this conflict should be viewed as a multi-year structural risk rather than a short-term incident. The Takaichi government is attempting to offset the burden of its conflict with China by strengthening its alignment with the United States. However, the possibility of a U.S.-China rapprochement ahead of their summit remains a source of anxiety for Tokyo. South Korea should avoid taking sides in the bilateral China-Japan conflict and instead pursue a dual-track approach to secure its own practical interests: assessing its rare earth supply chain risks and monitoring potential spillover from the Taiwan Strait.

I. Analysis of the Current Situation

The Meeting Between the Japanese Parliamentary Delegation and China’s International Liaison Department: A Situational Analysis

Background and Developments

In a Diet session last November, Prime Minister Sanae Takaichi stated that a blockade or armed occupation of Taiwan during a contingency could constitute a "situation that threatens Japan's survival" [1][3]. This remark directly linked the legal basis for the use of force by the Japan Self-Defense Forces to the Taiwan issue [1]. For China, the Taiwan issue is non-negotiable [1]. Immediately following the remark, Beijing began to pressure Japan by implementing export controls on rare earths and magnets [1].

Japan has pursued a dual-track approach of maintaining its defense buildup while attempting to contain conflict with China [3]. This is exemplified by its simultaneous pursuit of a ¥1.2 trillion defense budget request and expanded independent regional engagement on one hand, and its attempts to manage the relationship through parliamentary delegations on the other [3]. The recent visit to Beijing by a delegation of lawmakers from the Liberal Democratic Party, Komeito, and the Centrist Reform Alliance, led by Shinichi Isa, is an extension of these containment efforts. With official government-to-government channels strained, Japan has repeatedly tried to create breathing room through exchanges involving both ruling and opposition party lawmakers.

Current Situation

At the meeting, Luo Gang, Deputy Head of the Chinese Communist Party's International Liaison Department, stated unequivocally that China's policy toward Japan will not change unless Japan revises its position on Taiwan. This implies that Beijing has made a retraction or correction of Prime Minister Takaichi's remark a precondition. According to an EAI assessment, this conflict should be viewed as a multi-year structural risk rather than a short-term incident [1]. Japan's efforts to secure alternative supply sources—including deep-sea mining off Minamitorishima, developing technology to recover elements from industrial waste, and securing suppliers in countries like Australia—are all medium- to long-term projects that will take years to commercialize [1]. China's comparative advantage in the refining and processing stages is expected to remain secure for the next three to five years [1].

Separately, China's Ministry of Foreign Affairs stated it would curb the growth of "neo-militarism," targeting Japan's 2026 defense white paper and its ¥8.89 trillion defense budget request for fiscal year 2027 [13]. Foreign Ministry spokesperson Guo Jiakun escalated the rhetoric by criticizing the Japanese Ministry of Defense's policy of pursuing strike capabilities, linking it to the anniversary of the victory in the War of Resistance Against Japanese Aggression [13]. This is consistent with Luo Gang's hardline stance on the Taiwan issue and demonstrates that Beijing is sending pressure signals against Japan simultaneously through multiple channels.

Meanwhile, Prime Minister Takaichi is seeking a meeting with U.S. President Trump on the sidelines of international events like the UN General Assembly in September [2]. This reflects Tokyo's anxiety over the possibility that Washington might strike a tariff deal with Beijing ahead of the upcoming U.S.-China summit, as well as the potential for U.S. engagement with North Korea [2]. The prime minister is also attempting to appoint individuals with strong communication channels to the United States to key posts in a cabinet reshuffle, a move that can be interpreted as preparation for potential U.S. pressure on both economic and security fronts [7].

Key Actors and Positions

The Chinese Communist Party's International Liaison Department used this meeting to deliver a hardline message through a party-to-party channel rather than official government-to-government ones. Deputy Head Luo Gang's statement, which explicitly made a revision of Japan's position on Taiwan a precondition for any change in China's policy, suggests that Beijing is using the parliamentary exchange channel as a conduit for pressure, not a forum for dialogue. China's Ministry of Foreign Affairs is adding another layer to this pressure by separately raising the issues of Japan's defense white paper and budget [13].

The Japanese parliamentary delegation was dispatched in a composition that reflected the ruling coalition of the Liberal Democratic Party, Komeito, and the Centrist Reform Alliance. This indicates that the Takaichi government was seeking an alternative, political-level channel while official government-to-government ties were strained. However, Luo Gang's remarks ensured this attempt concluded without any tangible achievements.

Prime Minister Takaichi herself has little incentive to retract her statement on Taiwan. Given conservative domestic opinion and the need for consistency with her defense buildup policy, correcting the remark would carry a heavy political cost. Concurrently, her priority is to ensure Tokyo is not sidelined ahead of the U.S.-China summit, which she aims to manage through a meeting with President Trump [2][7].

Key Issues

The first key issue is Beijing's precondition demanding a retraction of the remark. Luo Gang's statement that China's policy toward Japan will not change without a correction of Prime Minister Takaichi's statement narrows the room for negotiation. The Japanese government is unlikely to accept this condition.

The second issue is the protracted nature of the conflict over rare earths. Since Japan's efforts to secure alternative suppliers will take years to commercialize [1], China's supply chain leverage will likely remain effective for the foreseeable future. This poses a direct supply chain risk for critical minerals in the realm of trade and economic security [1].

The third issue is how this conflict intersects with the broader framework of U.S.-China strategic competition. The China-Japan conflict over the Taiwan issue can be seen as a case where the repercussions of U.S.-China strategic competition in the Taiwan Strait have spilled over into a bilateral dispute [1]. Tokyo's vigilance regarding this interconnected dynamic is a key reason why Prime Minister Takaichi is rushing to coordinate with President Trump [2].

II. In-Depth Analysis

The Luo Gang Meeting with the Japanese Parliamentary Delegation: An In-Depth Analysis

1. Root Cause: The Uncompromising Nature of the Taiwan Issue

The fundamental reason the meeting failed to yield results lies in Beijing's cognitive framework regarding the Taiwan issue. For China, Taiwan is non-negotiable [1]. Deputy Head Luo Gang's statement was not an impromptu hardline remark; it was the official position delivered through a party channel, the Chinese Communist Party's International Liaison Department. This signals that Beijing intends to frame Prime Minister Takaichi's remark on a "situation that threatens Japan's survival" not as a localized diplomatic gaffe, but as a fundamental problem with Japan's entire security policy line.

Prime Minister Takaichi's remark directly linked the legal basis for the use of force by the Self-Defense Forces to the Taiwan issue [1]. This is the crucial point. Past statements on Taiwan by Japanese government officials have largely been confined to the realm of political rhetoric. However, acknowledging a "situation that threatens Japan's survival" touches upon the legal trigger for exercising the right of collective self-defense. From Beijing's perspective, the legal and institutional precedent created by the remark is more threatening than the words themselves. The "revision of position" demanded by Luo likely signifies not a simple apology, but the dismantling of this legal link.

Concurrently, Foreign Ministry spokesperson Guo Jiakun separately stated that China would curb the growth of "neo-militarism," targeting Japan's 2026 defense white paper and its ¥8.89 trillion defense budget request for fiscal year 2027 [13]. The timing of this statement, linked to the anniversary of the victory in the War of Resistance Against Japanese Aggression, coincides with Luo Gang's hardline position. This simultaneous messaging from both party and government channels is not a coincidence. It is evidence that Beijing has designed its pressure on Japan as a coordinated, state-level campaign, not as a series of isolated responses from individual ministries.

2. Structural Context

Political Structure: The Dual Nature of the Party-to-Party Channel

The visit to Beijing by Shinichi Isa's delegation was a Japanese attempt to create breathing room through exchanges involving both ruling and opposition lawmakers at a time when official government-to-government channels were strained. This approach has been a frequently used alternative route in the history of China-Japan relations. This instance, however, exposed the fundamental limits of that route's effectiveness. The International Liaison Department, by its nature as a party-to-party channel, has often been regarded as a conduit for more flexible messaging than formal government negotiations. Yet, Luo Gang used this channel not to leave room for dialogue, but to stipulate conditions. This implies that Beijing has redefined parliamentary exchange from an opportunity to improve relations into a vehicle for delivering political pressure. To the extent that expectations for managing the relationship through this channel existed in Japanese political circles, this meeting has demolished the foundation for them.

Economic Structure: The Long-Term Viability of the Rare Earths Card

The export controls on rare earths and magnets that Beijing introduced immediately after Takaichi's remark are functioning as a tool of structural pressure, not as a one-off retaliatory measure [1]. Japan's efforts to secure alternative sources—such as deep-sea mining off Minamitorishima, developing technology to recover elements from industrial waste, and securing suppliers in countries like Australia—are all medium- to long-term projects that will take years to commercialize [1]. China's comparative advantage in the refining and processing stages is expected to remain secure for the next three to five years [1]. This asymmetry is a structural condition that buys time for Beijing. As long as Japan is unable to secure an alternative supply chain in the short term, China can maintain both its hardline stance on the Taiwan issue and its economic leverage. Beijing's confidence in this economic superiority must be seen as the backdrop for Luo Gang's conditional hardline stance.

Security Structure: The Simultaneous Pursuit of Defense Buildup and Linkage to Taiwan

The Takaichi government is pursuing a dual-track policy: on one hand, a ¥1.2 trillion defense budget request and expanded independent regional engagement, and on the other, an attempt to contain conflict by dispatching a parliamentary delegation [3]. Japan's Ministry of Defense has requested a record defense budget of ¥8.9 trillion for fiscal year 2027, which prioritizes the expansion of strike capabilities, including unmanned platforms [14]. These two tracks undermine rather than offset each other. As long as Japan continues its defense buildup, conciliatory gestures like sending a parliamentary delegation are unlikely to be received in Beijing as sincere. Spokesperson Guo Jiakun's direct criticism of the defense white paper and budget was aimed at precisely this point [13]. As long as Japan simultaneously pursues a policy of strengthening its security and a policy of managing relations with China, the latter is likely to be dismissed as a mere byproduct of the former.

3. Historical Precedents and Comparative Cases

This is not the first time China has stipulated that another country must "revise" its position on an issue as a precondition for a policy change. Beijing has repeatedly used similar rhetoric in its disputes with neighboring countries in the South and East China Seas. The intensifying China-Taiwan competition around the Taiwan Strait can be understood in the same context. A representative case occurred at the Pacific Islands Forum (PIF) summit, where a Chinese special envoy called Taiwan's attendance "highly inappropriate" and warned of "consequences" [4][9][15]. Taiwanese Foreign Minister Lin Chia-lung decried this as "bullying" [11]. This incident demonstrates a pattern of Beijing applying harsh, conditional pressure even on third countries and third-party channels in matters related to Taiwan. Luo Gang's remarks to Japan can be seen as an extension of this broader pattern.

However, there is a crucial difference between the case of Japan and that of the Pacific Island nations. While the Pacific Island nations are in a position of weighing diplomatic recognition between China and Taiwan, Japan has already accepted the "One China" principle. The fact that Beijing is nonetheless applying conditional pressure of similar intensity on Japan can be interpreted as its intent to apply the same strict standards to any matter concerning Taiwan, regardless of the stability of its existing diplomatic relationships.

Precedents exist in past China-Japan relations where political disputes have led to economic retaliation. However, the current conflict over rare earths differs from past cases in its structural persistence. While it will take Japan years to secure alternative supply chains, Beijing's position on the Taiwan issue is a matter on which retreat is nearly impossible for domestic political reasons [1]. Because neither side has much incentive to back down in the short term, this conflict is more likely to evolve into a prolonged standoff than to follow the pattern of past one-off economic retaliations.

4. Key Variables Shaping Future Developments

The first variable is the language used regarding Taiwan in the revision of Japan's national security documents, scheduled for December [3]. Whether the Takaichi government softens its phrasing on the "situation that threatens Japan's survival" or maintains its current stance will determine the intensity of Beijing's subsequent response.

The second variable is the outcome of the U.S.-China summit. Prime Minister Takaichi's attempt to secure a meeting with President Trump at the UN General Assembly in September is driven by Tokyo's anxiety that Washington might strike a tariff deal with Beijing [2]. If the U.S. and China reach a compromise, Japan may find it difficult to count on American support in its confrontation with China. This could, in turn, increase Tokyo's incentive to soften its stance on Taiwan.

The third variable is the actual pace of progress in establishing alternative rare earth supply chains. If the Minamitorishima mining project or the technology for recovering elements from industrial waste reaches commercialization faster than anticipated, Japan's negotiating leverage would improve and weaken Beijing's economic leverage [1]. Conversely, delays in this progress would prolong Japan's exposure to economic pressure, which could fuel domestic political calls for softening its position on Taiwan.

The fourth variable is the extent to which China's domestic political calendar aligns with hardline public opinion on Japan. The timing of spokesperson Guo Jiakun's remarks, linked to the anniversary of the victory in the War of Resistance Against Japanese Aggression [13], suggests that Beijing is deliberately synchronizing domestic political events with its external pressure messaging. If such domestic political occasions are repeatedly used in this manner, a hardline policy toward Japan could become a fixed constant, subordinate to China's domestic political schedule, rather than a flexible stance shaped by specific negotiations.
