Summit diplomacy and relationship management

The tariff relationship moved through escalation and partial de-escalation. The United States opened Section 301 investigations covering China and a number of other trading partners; a domestic court ruling narrowed the tariff authority those measures rest on; and the Beijing summit produced reciprocal reductions on some goods together with renewed agricultural access. China applied countermeasures of its own, barring government procurement from dozens of US companies and keeping retaliation in reserve. Disputes also run through specific sectors: Chinese electric vehicles and the question of their access to the US market, soybean and beef purchases, and tariff evasion through third countries. Coverage divides less evenly here than elsewhere in the dyad. Chinese state media frame the measures as unilateral coercion outside the multilateral system. Western coverage is predominantly skeptical of the campaign — arguing it has raised costs and uncertainty for US industry and farmers while strengthening Beijing's position — and an argument that tariff pressure is producing results is comparatively rare in headline coverage.

Export controls are the principal instrument through which the United States acts on the technology relationship, and their operation has become two-sided. Washington maintains entity-list designations and licensing conditions on advanced chip sales, coordinates lithography controls with allied governments, and enforces against diversion — including a prosecution over the diversion of billions of dollars of Nvidia chips and a settlement with a US equipment maker over unlawful exports. Beijing's response has moved beyond objection: it has withheld approval for H200 imports that US authorities had cleared for export, conditioned approvals on its own terms, and pressed domestic substitution. Chinese firms have also acquired US chip tools through Southeast Asian intermediaries. Coverage divides on disjoint lines: Western, allied and specialist outlets treat the controls as protection of a lead with direct military relevance, while Chinese state media present them as suppression of legitimate development that disrupts global chip supply chains and is failing on its own terms.

Artificial intelligence is the strand where the capability gap has narrowed most visibly. Chinese models reached the frontier at lower training cost, Chinese firms began competing for users inside the US market, and both governments treated the field as strategic. The contest is conducted with every available commercial and regulatory instrument: the US Defense Department listed Chinese technology companies as supporting the Chinese military, drawing lawsuits from the firms named; a US AI developer accused a Chinese counterpart of obtaining illicit access to its models, and the Chinese firm restricted its employees from using the US developer's tools in turn; Washington issued warnings over model distillation; and Beijing blocked a US acquisition of a Chinese AI developer and tightened rules on outbound investment. Alongside the rivalry the two governments agreed to open an intergovernmental dialogue on artificial intelligence. Coverage divides on disjoint lines: Western, allied and specialist outlets describe a close race in which both sides use hard tactics, while Chinese state media attribute Chinese progress to domestic research investment and characterise US accusations and blacklisting as attempts to suppress a competitor.

Critical minerals are the strand where the asymmetry runs the other way. China holds a dominant share of rare-earth mining, refining and magnet production, and has used export licensing as an instrument — including placing two US rare-earth producers on its own export-control list. A bilateral arrangement on rare-earth supply has been in effect, with its extension discussed at the Beijing summit, though Chinese curbs continued to bind in the meantime. The US response is industrial rather than regulatory: a multibillion-dollar strategic stockpile, Defense Department offtake and investment arrangements with non-Chinese producers, and critical-minerals agreements concluded with the European Union and Japan. Third countries with their own deposits, including Brazil, have declined to align exclusively with either side. Coverage divides on disjoint lines: Western, allied and industry outlets treat the dependence as a strategic vulnerability to be engineered away, while Chinese state media present export licensing as lawful regulation of dual-use materials and the allied minerals agreements as exclusive blocs that fragment global trade.
