Why the Trump-Xi Summit’s Omission of Taiwan Raises Questions About US Arms-Export Law and the Legal Bounds of Bilateral Trade Agreements

The bilateral meeting between the United States President and the Chinese President, widely reported as the Trump-Xi summit, was formally summarized in a White House fact sheet that conspicuously omitted any mention of Taiwan, thereby creating a notable documentary gap in the public record of the encounter. During the summit, the two leaders declared that the United States and the People’s Republic of China had reached a series of trade and investment accords, encompassing a specific commitment by the United States to supply Boeing aircraft to Chinese commercial or civil operators under mutually agreed terms. In addition, the announced agreements incorporated a suite of agricultural transactions, wherein American producers would increase exports of key commodities to the Chinese market, reflecting an effort to deepen bilateral economic interdependence across multiple sectors. Beyond commercial matters, the joint statement highlighted a shared resolve to address Iran’s nuclear programme, with both parties asserting a common commitment to uphold the principles of nuclear non-proliferation and to support mechanisms that deter further nuclear enrichment activities by Tehran. The summit also featured a declaration that the United States and China would cooperate to ensure the uninterrupted flow of maritime traffic through the Strait of Hormuz, a strategic chokepoint whose security is deemed essential for global energy markets and international trade. Notwithstanding these extensive provisions, the President of the United States implied a potential revision of longstanding United States arms sales policy toward Taiwan, suggesting that Washington might reconsider the magnitude or nature of defense articles and services provided to the island. The implied policy shift was presented without an accompanying legislative or regulatory instrument, raising the prospect that any future adjustment to arms transfers would require adherence to established statutory frameworks governing defense exports and congressional oversight. The omission of Taiwan from the official fact sheet, juxtaposed with the President’s verbal indication of possible arms-sale reconsideration, creates a factual contrast that invites scrutiny of the procedural steps required under United States law to modify defense export arrangements. Because the fact sheet serves as the primary public summary of the summit’s outcomes, its silence on Taiwan may affect stakeholders’ expectations regarding the legal status of ongoing or future defense cooperation between the United States and the island entity. Overall, the convergence of trade, security, and diplomatic elements within the summit’s announced agenda, combined with the selective documentation of topics, underscores the importance of assessing how the declared agreements align with applicable United States statutes, regulations, and international obligations.

One question is whether the announced Boeing aircraft deal complies with the statutory requirements of the Arms Export Control Act, which mandates that any export of defense articles be preceded by a presidential determination of national security impact and a subsequent certificate from the Department of State. The answer may depend on whether the United States has filed the required notification to Congress under the Arms Export Control Act and the International Traffic in Arms Regulations, because failure to do so could constitute a breach of mandatory reporting obligations and trigger legal challenges.

Perhaps the more important legal issue is how the omission of Taiwan from the fact sheet interacts with the Taiwan Relations Act, which obliges the United States to provide Taiwan with defensive articles sufficient to maintain a credible self-defence capability. A court might examine whether any contemplated reconsideration of arms sales, as hinted by the President, would require a formal determination under the Arms Export Control Act and a concurrent assessment of compliance with the Taiwan Relations Act, thereby ensuring that any alteration respects the statutory framework governing U.S. defense support to Taiwan.

Another possible view concerns the joint commitment on Iran’s nuclear non-proliferation, raising the question of whether the United States can lawfully engage in any cooperation with China on this matter without violating the comprehensive sanctions regime administered by the Office of Foreign Assets Control. The legal position would turn on whether the United States has secured the necessary OFAC licensing authorisations for any joint activity that could be deemed to provide material support to Iran, and whether the stated commitment aligns with the statutory prohibitions embedded in the Iran Sanctions Act.

Perhaps the procedural significance lies in the declaration to safeguard navigation through the Strait of Hormuz, which may implicate the United Nations Convention on the Law of the Sea and the United States’ domestic authority under the Shipping Act to ensure free passage for commercial vessels. A fuller legal assessment would require clarity on whether any bilateral coordination announced at the summit translates into concrete regulatory measures, such as joint naval patrols or intelligence sharing, that would need to be grounded in both international maritime law and domestic statutory authorisations.

If later facts show that the United States proceeds with revised arms sales or implements the agreed security measures without adhering to the procedural safeguards prescribed by the Arms Export Control Act, the question may become whether affected parties could seek judicial review on grounds of procedural impropriety and violation of statutory duty. The safer legal view would depend upon whether the executive branch ensures that all announced agreements are accompanied by the requisite certifications, congressional notifications, and compliance checks, thereby preserving the rule of law and mitigating the risk of legal challenges to the summit’s outcomes.
