On Sunday, in a rare (pre-taped) sit-down interview that aired with CBS 60minutes, the question of a potential China/Taiwan conflict came up.
President Biden stated U.S. men and women would defend Taiwan in the event of an unprecedented Chinese invasion. Then according to 60 Minutes, a Whitehouse official clarified that U.S policy has not changed.
Does the United States and Taiwan have an alliance?
We agree with what we signed onto a long time ago. And that there's one China policy, and Taiwan makes their own judgments about their independence. We are not moving, we're not encouraging their being independent. We're not that's their decision. -President Biden
“As a leading democracy and a technological powerhouse, Taiwan is a key U.S. partner in the Indo-Pacific. Though the United States does not have diplomatic relations with Taiwan, we have a robust unofficial relationship.
The United States and Taiwan share similar values, deep commercial and economic links, and strong people-to-people ties, which form the bedrock of our friendship and serve as the impetus for expanding U.S. engagement with Taiwan”. (Source)
Does the Unites States have an agreement to defend Taiwan?
“The United States has no mutual defense treaty with Taiwan, as we do with Japan and South Korea. On the contrary, since the 1979 Taiwan Relations Act, Washington has explicitly recognized the island as a part of China. Since then, “strategic ambiguity” has governed U.S. Taiwan policy: Washington won’t support the island’s independence so long as China refrains from seizing it by force”. (Source)
For the second time this year Biden has said the U.S would defend Taiwan militarily. And, for the second time Whitehouse officials have toned it down saying that U.S policy has not changed.
