From North Korean missiles to scallop and sea urchin farming, Prime Minister Shinzo Abe and Russian President Vladimir Putin have a wide range of items on their agenda when the two meet Thursday in Moscow.

The summit is expected to focus on the joint economic development of the four Russian-held islands off the coast of Hokkaido that are claimed by both countries — known as the Northern Territories in Japan and the Southern Kurils in Russia.

The four islands include Etorofu, Kunashiri, Shikotan and the Habomai islet group.
