Secretary of State Antony Blinken has some.

The secretary declined to detail potential US responses [to a Russian invasion of Ukraine] but said Mr Biden cited the potential for “high-impact economic measures.”

And

If Beijing were to decide to try to change the status quo [vis-à-vis the Republic of China] unilaterally by force, it would be a very serious mistake[.]

Sure. What exactly might those high-impact economic measures be, and on what basis does Blinken—or Biden-Harris, for that matter—think Putin cares about those, given that he’ll have Ukraine under his control? What evidence do Blinken or Biden-Harris offer to suggest Putin has cared overmuch about past “economic measures?”

Blinken and Biden-Harris are carefully silent on all of that.

Further, what do Blinken or Biden-Harris suggest would be their corrective action for Beijing’s “mistake?” What makes either of them think Xi Jinping would care about any correction, since he’d already be occupying the RoC?

More careful silence.
