The US says the sale does not indicate a change to the "one China" policy

(CNN) The US' decision to go ahead with the sale of a $1.4 billion arms package to Taiwan threatens to undermine US-Chinese relations, China's ambassador to Washington said.

Speaking to the People's Daily newspaper Thursday, Ambassador Cui Tiankai said recent US moves eroded the trust built when US President Donald Trump met Chinese President Xi Jinping in Florida in April.

"US arms sales to Taiwan and the sanctions against Chinese enterprises have damaged the basis and mutual trust between the two countries, it also contradicts the spirit and consensus of the two leaders' meeting in Mar A Lago," said Cui.

A statement released by the Chinese Embassy in Washington said that the sale of arms to Taiwan "grossly interferes" in China's domestic affairs. "The Chinese side has lodged serious representation to the US side, and reserves every right to take further action," read the statement.

On Thursday, the Trump administration notified Congress of its plans to go ahead with the controversial arms package, the first such sale under President Trump.
