Japanese Prime Minister Shinzo Abe says the country's position remains unchanged regarding a peace treaty with Russia. Japan insists that the treaty should be signed after resolving the issue of the 4 Russian-held islands claimed by Japan.
He made the remark during a meeting with Komeito leader Natsuo Yamaguchi on Thursday after returning from Russia.
At an international conference in Vladivostok on Wednesday, Abe called on Russia to cooperate on a peace treaty between the two countries.
Russian President Vladimir Putin then proposed to sign a peace treaty with Japan by the end of the year without any preconditions.
In the meeting with Yamaguchi, Abe said he takes Putin's proposal as an expression of enthusiasm for a peace treaty.
He also said the Japanese government's policy remains unchanged, and a peace treaty should be signed after resolving the issue of the 4 Russian-held islands.
Russia controls the 4 islands. Japan claims them.
The Japanese government maintains the islands are an inherent part of Japan's territory. It says the islands were illegally occupied after World War Two.
