In May, President Joe Biden issued a stark warning to China: The U.S. would come to Taiwan's defense militarily if China were to invade.
"That's the commitment we made," Biden said in response to a question over the U.S.' intention to protect Taiwan. "We agree with the 'One China' policy. We signed on to it."
Although the White House quickly affirmed the president's comments did not reflect a policy shift, his remarks came at a time of heightened concern over China's interest in invading Taiwan after Russia's invasion of Ukraine.
Biden's warning contrasted with the U.S.' long-standing position of "strategic ambiguity" when it comes to Taiwan. That policy makes it unclear whether the U.S. would come to Taiwan's defense if China were to invade, the Brookings Institution's Michael O'Hanlon told CNBC in an interview.

Taiwan accounts for 64% of the total chip foundry market, according to data from TrendForce. Taiwan Semiconductor Manufacturing Company, or TSMC, accounted for 53% of total foundry revenue in 2021, according to TrendForce.
