Donald Trump has accused China of attempting to “interfere” in the US midterm elections because they don’t want him to win.
The US president did not offer any details to support the claim.
Mr Trump, who was chairing the UN Security Council for the first time, said: “They do not want me, or us, to win because I am the first president ever to challenge China on trade, and we are winning on trade.
“We are winning at every level.
“We don’t want them to meddle or interfere in upcoming (elections).”
US officials have not immediately responded to requests for comment after Mr Trump’s claims.
A representative from China who attended the meeting could be seen coughing into his hand and shrugging as the president spoke.
President Trump imposed tariffs on $200bn worth of Chinese goods on Monday, with Beijing accusing Washington of “economic intimidation”.
Beijing’s retaliatory tariffs on $60bn worth of US goods were due to go into effect soon after the US sanction.
Mr Trump’s claim comes amid an ongoing special counsel investigation into whether his campaign team colluded with Russia in the 2016 US election.
The are concerns that the November elections could also be vulnerable.
With the midterms less than two months away, US intelligence officials have said they are not seeing the intensity of the Russian intervention registered in 2016.
But they added they are concerned about activity from Russia, China, Iran and North Korea.
Mr Trump also used his moment chairing the Security Council meeting in New York to talk about nuclear proliferation, issuing a strong warning to nuclear-aspirant Iran.
He branded the country the “world’s leading sponsor of terror” fuelling “conflict around the region and far beyond.”
