Chinese state-run media have lashed out at U.S. President-elect Donald Trump's recent comments on Taiwan, with one newspaper calling the issue a "Pandora's box of lethal potential" that could upend the two powers' relationship.

In an interview with The Wall Street Journal published Friday, Trump again raised the prospect of using Taiwan as a bargaining chip in Sino-U.S. relations, saying that "everything is under negotiation, including 'one China.'"

In an editorial Sunday, the China Daily newspaper said that Beijing had endeavored to give Trump "the benefit of the doubt twice" after his unprecedented December phone call with Taiwan President Tsai Ing-wen and his remarks later that month that the "U.S. would not be bound by the 'one-China' policy." However, the editorial said, "doing the same wrong for a third time shows intent."
