Continental US airspace is massive and incredibly expensive to secure. Just look at the challenges the USSR faced during the Cold War. If US enemies can instill a multi-directional threat towards the North American continent and force massive buildup of AA there (to protect from, say, missiles in Cuba), they'll bleed out US defense resources easily. Attack from the North is difficult with Canada as a buffer, but plenty of states to threaten national security from the US South and Southeast.US worry about defending Taiwan, helping Ukraine, and other overseas conflicts but have utterly ignored securing its own homeland's airspace.

Because the talks will be all about reducing China's warheads and "guard rails" ie questioning the need for more weapons, US talk with "forked" tongue as our native brothers and sisters have said.
It's the Americans that wanted a discussion. China should make clear its reasonable terms, if nothing else, just to force Americans to reject it and exposing them for creating a nuclear arms race.As long as Russia remains as a player. They are going to insist China either cuts to 750 nukes with Russia having the other 750 while they keep 1500. They are not going to sign any agreements unless China handicaps themselves severely because Russia already has a lot of nukes.

What Russia does is in theory Russia's own concern, but if there is a preliminary agreement reached to downsize oversized nuclear arsenals, then China can surely make the Kremlin also gradually go down to a nuclear cap of 1500.
