North Korea's Kim Jong-un and Russia's Vladimir Putin have pledged to boost ties at their first ever summit.
The pair shook hands on Russky Island near the port city of Vladivostok, in Russia's far east.
Leaders are discussing peaceful resolution of the nuclear issue on the Korean Peninsula, ensuring security in Northeast Asia as a whole and the state of the bilateral relations, TASS said.
At their opening remarks the Russian and North Korean leaders referred to their two countries' long history of ties and Mr Putin said he wanted to help calm Korean tensions.
"I am confident your visit today to Russia will help us to better understand how we can resolve the situation on the Korean peninsula and what Russia can do to support the positive processes currently taking place," Mr Putin said.
Mr Kim said he hoped for "a very useful meeting in developing the relationship between the two countries, who have a long friendship and history, into a more stable and sound one".
