China’s Foreign Ministry on Monday said that United Stated President-elect Donald Trump is clear about Beijing’s position on Taiwan, reported Reuters. The country said it was in touch with Trump’s team regarding the same. Their statement comes only days after the New York businessman spoke to Taiwanese President Tsai Ing-wen on Friday.

China, on Saturday had said that it had lodged a complaint against the call to the “relevant side” in the US, without clarifying on who they approached against Trump’s action. “The whole world knows about the Chinese government’s position on the Taiwan issue. I think President-elect Trump and his team are also clear,” said ministry spokesperson Lu Kang.

On Sunday, Trump took to Twitter and criticised Beijing’s economic policy and it’s stand in the South China Sea dispute. “Did China ask us if it was OK to devalue their currency [making it hard for our companies to compete], heavily tax our products going into their country [the US doesn’t tax them] or to build a massive military complex in the middle of the South China Sea? I don’t think so!” Trump wrote on the micro blogging website. The US president-elect had said that his regime would be strict with China and label the country as a currency manipulator if he was elected to power. His position is being perceived as a potential threat to Sino-US relationship.

Lu, however, did not comment on Trump’s latest tweets against China. On the contrary, he stressed on the ”mutually beneficial” relation shared between the countries. “The China-US economic and trade relationship has over many years always been a highly mutually beneficial one, otherwise it couldn’t have developed the way it has today,” Lu said, adding that good relation between China and the US was in the interest of both.

China, Philippines, Vietnam, Taiwan, Malaysia and Brunei have been fighting over their claim on the resource-rich territory of the South China Sea for years. China has claimed nearly 90% of the territory that is defined by the nine-dash line and also issued a map to back its claims.
