"If he tries to sabotage the One China policy or harm China 's core interests, ultimately he will lift a rock only to crush his own toes," Chinese foreign minister Wang Yi said Monday in Switzerland according to comments posted on the ministry's web site.
China’s foreign minister warns USA
On Tuesday Chinese media sent another fusillade toward the "presumptuous and ill-guided" president-elect, slamming his approach to Taiwan as a recipe for disaster.
"Beijing should be prepared for the worst-case scenarios, particularly regarding Taiwan , as a presumptuous and ill-guided Trump looks set to usher in an era of turmoil," the state-run China Daily said in an editorial accompanied by a cartoon of the billionaire politician sitting on a powder keg.
"Trump's bloated and bloating ego may prevent him from seeing that is the likely outcome that lies ahead if he persists with this gamble."
US-China relations soar after Donald Trump phone call
The nationalistic Global Times newspaper warned Trump in its editorial Tuesday that "pride goes before a fall", and said he had lost the "strategic initiative" by revealing his strategy of "blackmailing" China .
Trump shocked the diplomatic establishment and angered Beijing by speaking directly with Taiwan 's leader Tsai Ing-wen after his election victory.
After fierce criticism of the move, he upped the ante, taking to Twitter to ask why he should not be allowed to speak to Tsai, then attacking Chinese foreign and economic policy.
The remarks were a step too far for Beijing, which had initially seemed resigned to taking a wait-and-see approach to the president-elect.
