Trump China visit live: Rubio hoping for ‘positive response’ to appeal for release of Hong Kong activist Jimmy Lai

US secretary of state Marco Rubio has said the US policy on Taiwan is “unchanged” after the summit talks between Donald Trump and Xi Jinping in Beijing.

“Our policies on that have not changed,” Rubio told NBC News. “It’s been pretty consistent across multiple presidential administrations, and remains consistent now.”

Xi warned Trump on Thursday that China and the US could come into conflict if the issue over self-ruled Taiwan – claimed by Beijing – is mishandled.

“The Taiwan question is the most important issue in China-US relations,” Xi said.
