U.S. President Donald Trump on Wednesday accused China of seeking to meddle in the Nov. 6 U.S. congressional elections, saying Beijing did not want his Republican Party to do well because of his pugnacious stance on trade.

"China has been attempting to interfere in our upcoming 2018 election, coming up in November. Against my administration," Trump told a U.N. Security Council meeting whose ostensible subject was nonproliferation of weapons of mass destruction.

Trump, chairing the council for the first time since becoming U.S. president, did not provide any evidence for his allegation, which China immediately rejected during the same meeting.
