At a congressional hearing, Acting Navy Secretary Hung Cao said the US is pausing a 14-billion-dollar weapons sale to Taiwan.

Just days earlier, Trump also signaled that he may hold off on the Taiwan arms sale.

For years, the US has used arms sales to Taiwan as a political tool — to pressure China, to send signals, and to keep tensions across the Taiwan Strait alive.

But now, the Trump administration seems to be moving more carefully.

Why? It is the most sensitive issue in China-US relations.

And Beijing has made its position very clear: China urges the US to exercise extra caution in handling the Taiwan question, stop sending any wrong message to "Taiwan independence" separatist forces, and safeguard peace and stability across the Taiwan Strait as well as the momentum of steady development of China-US relations with concrete actions.?
