China, meanwhile, was not amused. During the Cold War, the United States regarded Taipei as the legitimate government of China. All that changed in 1971 under Richard Nixon, when the United States recognized Beijing as the true government of China. China, over the decades, has resented Taiwan for thinking of itself as an independent entity; younger Taiwanese, in particular, seem to have no desire to reunite with Beijing. So it came as no surprise when, in response to Trump and Taiwan’s bonhomie, China sent an aircraft carrier through the straits of Taiwan in a move apparently designed to intimidate the island nation.
Since then, Trump seems to have tempered his boldness. He has criticized Jewish settlement expansion in the West Bank, after seemingly embracing it, and reaffirmed a tight Japan-U.S. relationship that he once said exploited the United States. And now he’s walking back his moves on Taiwan: On his first phone call with Chinese President Xi Jinping last Thursday, Trump said he would honor the One China policy.
This leaves Taiwan in a perilous place—Trump may renegotiate the status quo, or he may simply revert back to it. “We were kind of surprised that he was willing to take the call,” Lo Chih-Cheng, a Taiwanese ruling-party legislator who advises Tsai on foreign policy, said to me. “We were even more surprised when he tweeted it saying he took the call. More importantly, he said that the One-China policy should be questioned in some way. We were somewhat surprised by that.”
I Yuan, a research fellow at Taiwan’s Institute of International Relations at National Chengchi University, was encouraged that things appear to have “swung back to the normal track, which facilitates stable cross-straits relations,” after Trump acknowledged the One China policy. But he said the Trump administration continued to behave in unpredictable ways. “He created an inner circle when it comes to national security and exercises power swiftly and secretly by delegating powers to family members. This is something new. If you want to say this will create a more chaotic situation, it might,” Yuan said. It’s further proof that for America’s allies, guessing the direction of U.S. policy under Trump remains impossible.
Though it’s unclear if Trump knew it, relations between Taiwan and China were already at an eight-year low even before the call. President Tsai won her election after promising to take a cooler stance towards China than her predecessor, Ma Ying-Jeou, who emphasized closer economic and cultural ties with mainland China as the best path forward for Taiwan. Tsai, unlike her predecessor, refused to declare her administration’s support for the 1992 Consensus, which acknowledges Taiwan as an indivisible part of China, but implicitly commits it not to invade by force, and Taiwan to not formally declare independence. Tsai has never declared an outright desire for formal independence from China, but Beijing considers her refusal to accept the Consensus provocative enough. Her foreign policy has instead emphasized building closer political and economic ties with Southeast Asian countries, Japan, and the United States.
