US-Russia nuclear arms control talks remain stalled following the February 2026 expiration of the New START treaty, the last bilateral agreement limiting strategic warheads and delivery systems. Recent Kremlin statements emphasize that renewed negotiations would require lengthy expert-level discussions and have been delayed by differences over the Ukraine conflict. US officials have renewed calls for trilateral talks including China, an approach Beijing continues to reject due to its smaller arsenal. Diplomatic contacts have increased through envoys discussing energy projects and prisoner releases alongside war-related issues, yet no framework for new limits, verification, or data exchanges has emerged. Upcoming events such as the November 2026 APEC summit could provide opportunities for leader-level signals on risk reduction or informal compliance with prior central limits.
