Trump picks Twitter fight with China

He said did Beijing ask before building "a massive military complex in the middle of the South China Sea?"

Recently, with China's foreign currency reserves falling to the lowest since 2011, the Chinese central bank are believed to have sold the dollar to ease yuan's decline, in an attempt to curb record capital outflows- doing exactly the opposite of what Trump claims.

At the same time, though, the newspaper argued that China needs to be tactful and skillful in dealing with Trump, adding that it "should understand that Trump has two faces".

Trump made massive waves across the world by taking the unprecedented step of having a phone conversation with Taiwan's President Tsai Ing-wen on December 2, something that a US president has not done since President Jimmy Carter formally broke off USA diplomatic recognition of the Republic of China (Taiwan) in 1979.

Another wrote: "The only way for the White House to have one day in peace is to cancel Donald Trump's twitter account".

Trump will have additional interviews with new candidates for secretary of state in the coming week, Kellyanne Conway, Trump's senior adviser who managed his campaign, told reporters at Trump Tower on Sunday.

"I would just say to our counterparts in China that this was a moment of courtesy".

"I would much rather have Donald Trump talking to President Tsai than to Cuba's Raul Castro or Iran's Hasan Rouhani", Texas Senator Ted Cruz - Trump's main challenger and a fierce critic during this year's Republican primary race - tweeted on Saturday.

But a phone call and a few Tweets later, that view is starting to change quickly as many here are realizing his presidency may not be as predictable as many had originally hoped.

"The Taiwan issue has always been the most important and sensitive issue in Sino-US relations", he said. "The Chinese side in Beijing and Washington lodged solemn representations with the relevant side in the US The world is very clear on China's solemn position".

But the phone call initiated by the president Tsai Ing-Wen and the fact that it has been accepted by the President-elect, which has not happened since 1979, provoked China's anger.

"As for the motivations behind certain actions of President-elect Trump and his team", Lu continued, "I don't want to speculate, but we certainly must declare our stand and attitude on issues that affect China". It will offer clues to the directions that United States policies will adopt after president- elect assumes responsibilities on January 20, 2017.

Trump tweeted that Tsai had called him but Taiwan's Presidential spokesman Alex Huang told CNN that both sides agreed ahead of time before making contact, but would not give any further details including exactly when they agreed to the call.

China announced it has lodged a formal complaint over the 10-minute phone call.

China's Foreign Ministry said it had lodged "stern representations" with what it called the "relevant U.S. side", urging caution on the issue.

Taiwan split from the Chinese mainland in 1949.
