The Trump-Xi Washington Summit: The '3T' Framework of Taiwan, Tariffs, and AI, and South Korea's Dual-Track Response Challenge

Executive Summary

The Trump-Xi Washington summit is an extension of the managed competition from the May Beijing meeting, continuing the “3T” framework of Taiwan, tariffs, and AI. An extension of the Busan trade truce is expected to be a key outcome, but in return, a deferral of arms sales to Taiwan and restraint on technology sanctions are likely to be exchanged. However, the Taiwan issue is a structural problem where Beijing's red line conflicts with Washington's domestic legal obligations, making a fundamental resolution difficult. The dialogue on AI safety is also likely to be carried over, with disagreements over its definition unresolved. A dual-track structure is expected to persist, where technology control measures against China accumulate on a separate regulatory track (e.g., the U.S. Department of Commerce, FCC), independent of symbolic agreements at the diplomatic level. South Korea needs to separate security-linked issues from commercial domains in its semiconductor and secondary battery supply chains, maintain separate channels with Taiwan, and engage in proactive coordination with the United States.

I. Situational Analysis

The Trump-Xi Washington Summit: Situational Analysis

1. Background and Developments

This summit is not a sudden event. It is a follow-up measure agreed upon during President Trump's visit to Beijing last May [7][9]. At that time, the “3Ts”—trade, technology, and Taiwan—formed the framework of the agenda, and the same framework is repeated at this Washington summit [7]. The AI domain, however, carries a different sense of urgency than it did in May. In early September, Anthropic CEO Dario Amodei publicly called for regulating the pace of AI development, and with OpenAI's Sam Altman and SpaceX's Elon Musk also agreeing, concerns about the risks of runaway AI have spread [16]. This context has added new weight to the AI agenda for this summit.

Xi Jinping's visit to the U.S. is his first state visit in 11 years [8][12]. Washington has prepared an exceptional reception. The schedule includes President Trump personally welcoming him at Joint Base Andrews, a flyover by a B-2 Spirit and F-22 squadron, and a separate meeting for First Lady Melania Trump with Peng Liyuan [8][10]. Whereas the 2023 APEC meeting in San Francisco was aimed at mending relations strained by the spy balloon incident, this visit is a continuation of relationship management, building on the preceding summit diplomacy of the May visit to China [6][9].

2. Current Situation

On September 20, just before the summit, preliminary coordination talks were held in New York between U.S. Treasury Secretary Besant and Chinese Vice Premier He Lifeng [17][20]. The Chinese negotiating team was led by He Lifeng, a close aide to Xi Jinping [17]. However, it is reported that no significant progress was made on the Taiwan issue [17]. Professor Zhou Bo of Tsinghua University lent weight to the possibility of maintaining the truce, stating, “The degree to which the U.S. depends on China for securing goods necessary for daily life is greater than China's dependence on the U.S.” [17]. This statement shows the growing belief within Beijing that it holds the upper hand in negotiations with the U.S.

The Brookings Institution believes the headline of this visit is likely to be an agreement to extend the trade truce agreed upon in Busan last October [11]. In return, Xi Jinping is expected to demand restraint from Trump on Taiwan, new tariffs, and technology-related sanctions [11]. Indeed, multiple media outlets, citing Reuters, have confirmed reports that Xi will press for a halt to arms sales to Taiwan based on the 1982 U.S.-China Joint Communiqué [12][18]. There is also speculation that he may raise this issue during a visit to the U.S. National Archives [12]. The Trump administration currently has a new $14 billion arms package for Taiwan on hold [12].

Foreign Policy predicts that a dramatic breakthrough should not be expected from this summit. The view is that while trade, minerals, and AI will be on the agenda, the outcomes will be limited [14]. The Atlantic Council also assesses that the two sides have only maintained an “uneasy lull” over the past year and that this is not a true détente [5]. This means a tightrope walk to avoid escalation while testing each other's red lines is ongoing [5]. The Nikkei Shimbun predicted that with the expiration of the Busan trade truce approaching, the two countries would simultaneously pursue “small achievements and conflict avoidance” [15].

3. Key Actors and Positions

The U.S. sideprioritizes securing tangible economic results. The Hankyoreh analyzes that the U.S. is focused on obtaining visible achievements, such as increased purchases of agricultural products [1]. Ahead of the summit, President Trump invited a large number of American Big Tech CEOs to the state dinner [4]. This is interpreted as a move to place the voices of the AI industry near the negotiating table. Senior U.S. administration officials confirmed to Reuters and AP that trade and tariffs, rare earth supply chains, and AI issues are the core topics of discussion for this summit [4].

The Chinese sideprioritizes preventing the reignition of the trade war and maintaining “strategic stability” [1]. Beijing is known to have set a red line that it could cancel the summit itself if new arms sales to Taiwan are approved [3][9]. An EAI analysis notes, “The Taiwan issue is solidifying into a structural red line rather than a bargaining chip” [3]. This means that in this summit, the Taiwan issue is being treated as a line not to be crossed, rather than an object of negotiation.

Taiwanis being treated as a subject of negotiation in this framework, not a party to it. While the U.S. officially recognizes the One China principle, it has maintained the practice of selling arms to Taiwan [9]. The possibility is now being raised that this practice itself could be on the bargaining table at this summit.

Japanis mentioned as an example of an ally that engaged in prior communication out of concern of being excluded. Prime Minister Takaichi's preliminary actions are an example of this [9]. This reflects concerns that the results of bilateral U.S.-China negotiations could be decided without regard for the interests of regional allies.

4. Summary of Key Issues

First is the issue of arms sales to Taiwan. China's demands, based on the 1982 Joint Communiqué, are intertwined with the reality of a pending $14 billion arms package [12]. Unlike trade issues, this matter has little room for compromise.

Second is the gap in the definition of safety surrounding AI. An EAI analysis points out, “The gap in the concept itself is not narrowing, as President Trump's rejection of the pace-regulation argument clashes with China's demand to share authority in defining safety” [3]. With growing concerns from the AI industry about a runaway scenario, how the two sides will coordinate on a safety framework is a key point of interest [16].

Third is whether the trade truce, centered on tariffs and rare earths, will be extended. With the expiration of the Busan agreement imminent [15][19], the prevailing view is that the summit will likely result in a level of “managed competition” [1][5][14]. However, EAI notes that the diplomatic track and the regulatory agency track (e.g., FCC) are already operating separately, making it highly probable that individual export control measures will accumulate independently, regardless of any symbolic agreement at the summit [3][6]. This suggests that even if an agreement is reached at the summit, its effectiveness may be structurally limited.

II. In-Depth Analysis

The Trump-Xi Washington Summit: In-Depth Analysis

1. Analysis of Root Causes

The reason this summit is once again repeating the same 3T framework of Taiwan, tariffs, and AI from the May Beijing meeting is simple: none of these three issues are conflicts that can be resolved through negotiation. Beijing defines the Taiwan issue as a matter of territorial sovereignty. It is a red line, not a bargaining chip [12][18]. From Washington's perspective, arms sales to Taiwan are a domestic legal obligation based on the Taiwan Relations Act. It is not a matter that can be deferred by a summit agreement. This structural asymmetry is the fundamental reason why the same issues resurface at every summit.

The root cause of the tariff issue lies in the structure of interdependence between the two countries. Professor Zhou Bo of Tsinghua University assesses, “The degree to which the U.S. depends on China for securing goods necessary for daily life is greater than China's dependence on the U.S.” [17]. This asymmetric interdependence gives Beijing the confidence that it does not need to be anxious in negotiations. The leverage China holds in the supply chains for rare earths and critical minerals acts as a mechanism to deter the reignition of the tariff war [1][4].

The fundamental reason the AI agenda carries a new sense of urgency at this summit is the gap between the speed of technological development and the ability to control it. The incident where Anthropic CEO Dario Amodei publicly called for regulating the pace of AI development, with executives from OpenAI and SpaceX agreeing, signifies that even companies are acknowledging the risk of losing control [16]. The Asahi Shimbun points to the successive discoveries of cyberattacks on other companies' systems during the development and testing processes of U.S. AI firms [16]. It argues that concerns about AI going rogue beyond human intention were the direct trigger for safety discussions [16]. This shows that the AI issue, previously handled within the framework of U.S.-China strategic competition, is now shifting into a matter of joint risk management for both countries.

2. Structural Context

The most prominent feature of the political structure is that Xi Jinping's negotiating power is relatively free from domestic political burdens. Vice Premier He Lifeng, who led the negotiating team, is considered a close aide to Xi [17]. The Chinese side maintained a consistent message even in the preliminary negotiations in New York. This is an example of how a centralized decision-making structure supports consistency in negotiation strategy. In contrast, President Trump is pressed by the political need to show tangible economic results, such as increased agricultural purchases, to his domestic audience [1]. This asymmetry is a structural factor that buys Beijing time at the negotiating table.

In the economic security structure, the expiration date of the Busan trade truce acts as a key variable [15][19]. The issues of tariffs, rare earths, and AI are intertwined with whether this truce is extended. Brookings believes the headline of this summit is likely to be an agreement to extend the Busan truce [11]. It predicts that a trade-off structure will be established where, in return, Xi demands restraint from Trump on Taiwan, new tariffs, and technology sanctions [11]. This suggests a structure where compromises in the trade and economic security domains are used as a buffer for the Taiwan issue, a security domain. However, it is difficult for this exchange to be explicitly stated in an actual agreement. The U.S. regulatory track is accumulating technology control measures against China separately from the diplomatic track, so even if a verbal understanding is reached between the leaders, there is a high probability that individual measures at the working level could nullify it [6][9].

In the security structure, the very fact that the new $14 billion arms package for Taiwan remains unapproved is evidence of tension [12]. The U.S. bringing this issue to the summit without approving it can be interpreted as an intention to keep it as negotiating leverage. At the same time, Beijing intends to use the symbolic occasion of a visit to the National Archives to once again evoke the 1982 Joint Communiqué [12][18]. This is an attempt to preemptively frame the issue through a legal basis. It is highly likely that the dual structure, in which the U.S. side acknowledges the One China principle while simultaneously fulfilling its arms sales obligations under the Taiwan Relations Act, will be maintained this time as well.

3. Historical Precedents and Comparison with Similar Cases

Comparing this summit with the U.S.-China summit held on the sidelines of the 2023 APEC meeting in San Francisco clarifies its nature. That was a crisis-management-style summit aimed at mending relations strained by the spy balloon incident [6][9]. This summit is different in nature as it is a continuation of relationship management, building on the preceding summit diplomacy of the May Beijing meeting [6][9]. The distinguishing feature is that it is not a post-crisis patch-up but rather routine management conducted through already stabilized channels.

The Busan trade truce (October 2025) is also an important precedent [11][19]. The fact that the truce agreed upon at that time was nearing its expiration just before this summit shows a pattern in which U.S.-China trade agreements are not permanent solutions but repeated temporary fixes [15][19]. This is the basis for the Nikkei Shimbun's prediction that “small achievements and conflict avoidance” will be pursued simultaneously at this summit as well [15]. The method of re-invoking the August 17, 1982, Joint Communiqué on the Taiwan issue is also not a new card. Beijing has protested based on this communiqué in the past whenever the U.S. has sold arms to Taiwan. However, the rhetorical intensity is higher this time, as it intends to use the symbolic venue of the National Archives [12].

The discussion on AI safety has the potential to be structurally compared to past nuclear arms control negotiations. However, a crucial difference is the absence of a verification system. While inspection and verification mechanisms for nuclear weapons were institutionalized during the Cold War, there is not even a common definition of AI capabilities and risks agreed upon between the U.S. and China. The AI safety dialogue to be held at this summit is likely to remain in the initial stages of this definition problem [2][16].

4. Key Variables Shaping Developments

The most direct variable is the approval of the $14 billion arms sales package to Taiwan [12]. If President Trump approves it before or after the summit, Beijing could react strongly, shaking the entire outcome of the summit. Conversely, if he continues to defer approval, it could be interpreted as a signal of concession to Beijing.

The second variable is the specificity of the agreement to extend the Busan trade truce [11][15]. Depending on whether it is merely a reaffirmation of the truce or is accompanied by easing measures on specific items like rare earths and semiconductors, the risk calculations for regional supply chain actors, including South Korea, will change [4][13].

The third variable is whether the AI safety dialogue will be institutionalized. In a situation where U.S. Big Tech executives like Amodei, Altman, and Musk have publicly called for regulating the pace [16], whether the summit elevates this into a permanent bilateral consultative body or it ends as a one-time mention will determine the future management of U.S.-China technology competition.

The fourth variable is the reaction of hardliners on China in the U.S. Congress. Even if a verbal understanding is reached between the leaders, if Congress and regulatory agencies continue to accumulate individual export control measures, the political sustainability of the agreement becomes structurally fragile [6][9]. The combination of these four variables will determine whether this summit remains at the level of “strategic stability management” or produces unexpected friction.
