Japan after the South Korean government lifted the 30-year ban on cultural exchange with Japan that had been in place since 1948. Korean pop cultural products' success in the Japanese market is partially explained by the borrowing of Japanese ideas such as the star-marketing system and heavy promotion of new television shows and music. Korean dramas such as "Winter Sonata" and "Coffee Prince," as well as K-pop artists such as BIGBANG and SHINee are very popular with Japanese consumers. Most recently, South Korean President Moon Jae-in met with Japanese Prime Minister Shinzo Abe at the 2017 G-20 Summit in Hamburg, Germany
Japan–Russia relations leaders decided to sign off on joint projects in five areas — aquaculture, greenhouse farming, tourism, wind power and waste reduction. At the 2018 Thirteenth East Asia Summit in Singapore, Shinzo Abe followed up on a proposal from Vladimir Putin to sign a peace treaty without preconditions by the end of the year. He said that the leaders would seek a peace treaty to the terms of the 1956 Soviet–Japanese Joint Declaration. The declaration gave Japan the Habomai islet group and Shikotan while the Soviet Union claimed the remaining islands, but the United States did not allow the 1956 treaty.
