Trump-Xi Summit: What will Trump announce by May 22?

Market context

The question is whether Donald Trump will formally announce a cut, suspension or removal of tariffs on China before the market closes. That is a higher bar than signalling talks or saying both sides are making progress. In the Trump-Xi meetings this week, the public emphasis has been on stabilising ties, trade, fentanyl and wider strategic issues, rather than on immediate tariff relief. Recent coverage from CFR and CSIS suggests both sides are using the summit to buy time and preserve leverage, which fits a market priced below one-in-three for a clear tariff announcement.

Comparable episodes point to caution. Trump has often used tariff policy as a bargaining tool, making some announcements only after explicit concessions, while leaving talks in place when he wants to keep pressure on Beijing. The current reporting also shows China pressing for broader political and economic stability, including Taiwan-related language and market access, rather than focusing purely on tariffs. That makes a one-step tariff concession less likely unless it is tied to a larger, pre-agreed package.

For traders, the main catalysts are a joint statement, a White House readout, or a direct Trump remark on Air Force One or in a press event that names China and clearly alters tariffs. The key distinction is between rhetoric about “good talks” and a definitive policy change. Reuters-style reporting on any signed memorandum, schedule for follow-up negotiations, or Treasury/USTR announcement would matter most; absent that, the most likely outcome remains no formal tariff reduction by the deadline.
