Parliamentary leaders from the Asia-Pacific region will start a four-day meeting in the Russian Far East city Vladivostok on Monday amid deadlocked tension on the Korean Peninsula and a territorial dispute between China and Japan.

Chinese top legislator Wu Bangguo arrived in Vladivostok on Sunday afternoon for the 21st Annual Meeting of Asia-Pacific Parliamentary Forum. It is the first time a Chinese top legislator has gone abroad to attend the forum.

Wu, chairman of the Standing Committee of China's National People's Congress, China's top legislative body, is expected to deliver a speech and have several meetings with counterparts from the region.
