"Large-scale infrastructure projects will contribute to Northeast Asia's peace and prosperity," a joint statement said.

Russian President Vladimir Putin met with South Korean President Moon Jae-in on Friday in the Kremlin, where they agreed on strategies to achieve peace in the Korean peninsula and further connect North and South Korea with Russia and Asia.

On the agenda is investing in infrastructure projects to directly link South Korea and North Korea with Russia. These plans are, however, currently blocked by sanctions imposed on North Korea.

Putin and Moon agreed to conduct joint research in the fields of electricity, gas and railways in order to advance cooperative projects between North Korea, Russia and South Korea: "Large-scale infrastructure projects will contribute to Northeast Asia's peace and prosperity." 

Railway projects are of particular interest, with plans underway to cooperate on research to connect the Trans-Siberian Railway with the Trans-Korean Railway, through North Korea.

Both leaders agreed that last week's historic summit in Singapore between U.S. President Donald Trump and North Korean leader Kim Jong Un was a positive step toward peace and denuclearization.

A joint statement signed by the presidents promised to "continue joint efforts to establish complete denuclearization on the Korean peninsula and secure permanent peace and stability on the peninsula and Northeast Asia."
