The ministry said Sergei Lavrov will be in North Korea on Wednesday and Thursday, but did not specify any meetings or the aims of the trip.
North Korean leader Kim Jong Un travelled to Russia last month to meet President Vladimir Putin and visit key military sites, triggering speculation about a possible North Korean plan to refill Russia’s munition stores that have been drained by the protracted conflict with Ukraine.
White House National Security Council spokesman John Kirby said that the US believes Mr Kim is seeking sophisticated Russian weapons technologies in return for the munitions to boost North Korea’s military and nuclear programme.
The White House released images that it said show the containers were loaded onto a Russian-flagged ship before being moved via train to south-western Russia.
The containers were shipped between September 7 and October 1, according to the White House.
Mr Lavrov was in Beijing on Monday ahead of an expected visit by Vladimir Putin.
Mr Putin is expected to attend the Belt and Road Forum in the Chinese capital on Tuesday and Wednesday, his first trip outside Russia since the Hague-based International Criminal Court issued a warrant for him in March over the deportation of children from Ukraine.
On Monday China's foreign minister Wang Yi met with Mr Lavrov and exchanged views on the Israel-Hamas conflict, the Chinese foreign ministry said.
The urgent task is a ceasefire and building of a humanitarian aid channel, Wang said in the meeting.
Mr Wang also urged China and Russia to deepen strategic mutual trust, his ministry said.
