The Taiwanese government responds after US President Donald Trump's trip to China and his call for the two countries to "cool down".

President Donald Trump is kicking off the busiest portion of his three-day visit to China. It's a trip that may end up focusing more on pageantry and symbolism than major bilateral breakthroughs.

The president said a potential arms deal for Taiwan was a “very good negotiating chip” in talks with Beijing. His words raise questions about the steadfastness of U.S. support.

Trump and Xi are set to meet in Beijing with tariffs, Taiwan tensions and the Iran conflict on the agenda as the U.S.-China relationship faces a critical test.

Donald Trump has cast doubt on a $14 billion weapons package for Taiwan after talks with Xi Jinping in Beijing, raising urgent questions about US commitment to the island and whether the two superpowers can avoid the so-called Thucydides Trap.

Speaking to reporters as he flew back on Air Force One on Friday, Trump said he’d not decided on the sale, but he added, “I will make a determination.”

At the end of the two-day summit, President Trump said that Chinese leader Xi Jinping offered to help with the war in Iran and promised to buy more American farm and energy products.
