Beijing (Agencies): China has urged the United States (US) to stop slandering Beijing after President Donald Trump accused the Asian giant of trying to interfere in upcoming American congressional elections.

Geng Shuang, a foreign ministry spokesman, told reporters at a regular briefing in Beijing that the Chinese government does not interfere in other countries' internal affairs.

Trump said on Wednesday as he chaired the United Nations Security Council for the first time that China was meddling in the elections because it opposes his tough trade policies. The White House provided scant evidence of anything akin to the level of Russia's meddling in the 2016 presidential election.

In Beijing, Geng said China urged the US to “stop making unwarranted accusations and slanders against China and stop the words and deeds that harm bilateral ties and the fundamental interest of the two peoples".

Trump made his accusation against the backdrop of the special counsel's investigation into Russian interference in the last election to help him and amid concerns that this November's elections could also be vulnerable.

Asked later what evidence he had, Trump said there was “plenty” but didn't immediately provide details, suggesting that some of the material was classified. Instead, he zeroed in on China 's efforts to flood the US heartland with ads and statements against Trump 's billions of dollars in tariffs on Chinese goods.

Trump added: “I don't like it when they attack our farmers and I don't like it when they put out false messages. But besides that, we learned that they are trying to meddle in our elections and we're not going to let that happen just as we're not going to let that happen with Russia.”
