Mr Wang, speaking to reporters at a joint briefing with his Mongolian counterpart, said that China has an open attitude on solutions to the North Korean nuclear issue, but that parties should be consultative.
In late November, North Korea tested its most advanced intercontinental ballistic missile yet, putting the continental United States within range and increasing pressure on US President Donald Trump to deal with the nuclear-armed nation.
North Korea’s Committee for the Peaceful Reunification of the Country called President Trump “insane” on Sunday.
It said air drills between the United States and the South would “push the already acute situation on the Korean peninsula to the brink of nuclear war”.
Mr Wang is expected to visit New Delhi in December to attend a regional forum, according to Indian media reports.
The meeting could help to calm the two countries after a protracted border dispute at the remote Doklam plateau.
