Prime Minister Yoshihiko Noda said Saturday that Japan's participation in the Trans-Pacific Partnership free-trade talks will be included in the Democratic Party of Japan's platform for the next general election.

"We will simultaneously pursue the TPP and a trilateral free-trade agreement among Japan, China and South Korea. This stance will be outlined in our election manifesto," Noda told reporters in Fukuoka.

Japan is currently embroiled in territorial rows with both nations, and trade with China is particularly suffering as a result.
