Recent diplomatic engagement between the Trump administration and Russia centers on Ukraine peace efforts, including a October 9 phone call between the presidents and a October 21 meeting in St. Petersburg between U.S. envoy Steve Witkoff and Vladimir Putin. These talks produced agreement in principle to resume trilateral negotiations after November 10 and floated a possible trilateral summit with Xi Jinping on the sidelines of the November APEC gathering in China. Traders assess these developments, alongside ongoing economic and prisoner-related gestures, as elevating the near-term odds of a direct Trump-Putin encounter before year-end deadlines. Resolution hinges on verifiable in-person meetings amid shifting negotiation timelines.
