The Section 301 investigation launched by the Office of the United States Trade Representative (USTR) in March 2026 is presented as a response to forced labor. But looking at the investigation report released in June and the additional tariffs proposed, the real goal appears to be something else entirely.
The survey was not designed to assess whether forced labor exists in specific countries; rather, its aim is to determine whether countries have systems in place to prohibit imports produced by forced labor and whether they enforce them effectively.
The proposed tariffs cannot, however, be explained solely by human rights concerns. Thailand, Vietnam and the Philippines do not have import ban systems in place that meet U.S. standards and face a tariff rate of 12.5 percent. Malaysia and Cambodia also have no such systems, but face tariffs of just 10 percent.
Malaysia has committed to introducing such a system within two years of its reciprocal trade agreement with the United States taking effect in 2025; Cambodia has made a similar commitment and strengthened enforcement of labor laws. In short, the United States evaluates countries to determine whether they have agreed to Washington’s trade terms and commitments. US Trade Representative Jamieson Greer highlighted this; according to the June 5 edition of Business timeit intends to force countries to respect trade agreements signed over the past year.
If forced labor were the main focus, the focus would be squarely on human rights and labor standards. This Section 301 investigation is, in fact, an extension of trade negotiations and not a human rights investigation.
Thailand and Vietnam remain at the framework agreement stage, leaving room for further negotiations. The two countries should study the agreements reached by Indonesia and Malaysia, identify what Washington really wants and shape their responses to advance ASEAN integration.
From bilateral to collective
The lesson from the reciprocal tariff negotiations is that ASEAN member states negotiated individually rather than collectively and, in doing so, missed an opportunity to turn U.S. external pressure into a driver of regional integration. Three corrective actions are necessary. First, institutional reforms demanded by the United States, such as customs procedures and certification systems, should be pursued within the framework of common ASEAN objectives. Second, the market opening and removal of non-tariff barriers promised to the United States should be extended to all trading partners in accordance with the WTO’s most favored nation principle and used to advance the development of the ASEAN single market. Third, ASEAN should collectively implement measures to prevent export circumvention and harmonize rules of origin, channeling Chinese investment towards the modernization of regional industries.
During the 2025 reciprocal tariff negotiations, individual ASEAN countries faced pressure to make concessions. Although the bloc advocates a single market and a single production base, the various compromises made by countries on non-tariff barriers, customs procedures and certification systems now make it more difficult to treat ASEAN as a single market.
Many of the institutional reforms sought by the United States align with ASEAN’s own integration agenda: streamlining customs processes, digitizing customs clearance, improving regulatory transparency, harmonizing authorization and approval procedures, and mutual recognition of certification systems are all priorities of the ASEAN Economic Community (AEC). Viewing them as challenges shared by ASEAN would allow concessions to the United States to serve doubly as a stimulus to regional integration.
ASEAN, as an advocate of free trade under WTO rules, should also ensure that any elimination of non-tariff barriers agreed with the United States is extended to all trading partners, in line with the most favored nation (MFN) principle.
When it comes to circumventing exports, ASEAN has both an external and internal reason to act. Washington sees Chinese investment in the region as a key factor in export circumvention; but local industries are also frustrated by their governments’ inability to manage the flood of semi-finished and intermediate goods from China. Collective measures to combat circumvention and boost local purchasing would serve both goals, facilitating regional industrial modernization and spurring the growth of supporting industries.
Forced labor is not the real goal, and ASEAN is not asked to resist the United States. Rather, the challenge is whether this can turn US pressure into a catalyst for deeper regional integration. If it succeeds in harmonizing customs procedures and regulations and dismantling non-tariff barriers, Section 301 risks being remembered not as a tool of trade coercion, but as the moment when ASEAN took a decisive step towards operating as a single market rather than eleven separate markets.
