US Trade Representative Jamieson Greer, in an interview on Bloomberg Television on September 21, 2026, discussed several key trade issues, including ongoing negotiations with China, the possibility of a diesel export ban, and the state of relations with Canada. His comments come ahead of the highly anticipated summit between US President Donald Trump and Chinese President Xi Jinping.

Regarding China, Greer indicated that discussions are continuing on a potential extension of the current tariff ceasefire, which is set to expire on November 10. While an immediate extension was not expected, Greer expressed optimism that both sides desire further talks, suggesting that Washington could support a three to six-month extension. This signals the US's willingness to maintain dialogue despite existing divisions on terms.

Greer also addressed the possibility of a diesel export ban and the ongoing renegotiation of the USMCA agreement with Canada. These discussions highlight the broader trade agenda and the various fronts on which the US is engaged in economic diplomacy.
