North Korea’s Kim Jong Un and Vladimir Putin have discussed “possibilities” for military cooperation, in a highly scrutinized meeting for a suspected arms deal.

The pair met on Wednesday at the Vostochny space center after Mr. Kim arrived in his private armored train. Mr. Putin also said he would help Pyongyang develop satellites.

Citing historical ties between the Soviet Union and North Korea, Mr. Putin welcomed his counterpart with the Russian proverb “an old friend is better than two new ones”.

Asked if Russia would help North Korea build satellites, Mr. Putin said “this is why we’ve come to Vostochny Cosmodrome”, Russian media reported.

Mr. Putin also said they would “discuss all topics” when asked if he would talk to Mr. Kim about a weapons deal.

Meanwhile, Mr. Kim appeared to express support for Mr. Putin’s war in Ukraine.

“Russia has risen to a sacred fight to protect its sovereignty and security against the hegemonic forces” of the West, Mr. Kim told Mr. Putin.

“We will always support the decisions of President Putin and the Russian leadership… and we will be together in the fight against imperialism.”

The North Korean leader is expected to oversee a display of Russian warships later, as well as visit several factories and stop by the eastern city of Vladivostok on his way home. It is not known how long he will stay in Russia.
