U.S. President Donald Trump said on Wednesday he would speak with Taiwan’s President Lai Ching-te, an unprecedented move that could roil U.S.-China relations.
China's foreign ministry urged the U.S. to "handle the Taiwan issue with extreme caution."
It was the second time Trump mentioned speaking to Lai, after first suggesting it following a meeting with Xi Jinping.
Taiwan said it would welcome the call, but no date has been confirmed.
China views Taiwan as part of its territory and considers high-level engagements as interference.
In 2022, China held major war games after Nancy Pelosi's visit to Taiwan.
Trump's administration approved an $11 billion arms sale to Taiwan in December.
Taiwan rejects China's sovereignty claims and says it is independent.
The U.S. maintains a "One China" policy but continues arms sales to Taiwan.
In 2016, Trump spoke with Taiwan's president; China reacted mildly.
