China will suspend its import on Japanese seafood products atter a diplomatic spat brought on by recent comments by Japan's prime minister.

China defence ministry said on Monday it has lodged representations with the United States over its arms sale to Taiwan, vowing to take "all necessary" measures to defend national sovereignty and territorial integrity.

Tension between Japan and China has escalated over the new Japanese leader's suggestion Tokyo could intervene militarily if Beijing attacks Taiwan.

China may conquer Taiwan through energy blockade and gray-zone tactics rather than military invasion, new defense study reveals. Beijing's strategy targets fuel imports.

BEIJING: China urges Japan to stop overstepping the line, retract its erroneous words and deeds, and honor its commitment to China with concrete actions, Chinese Foreign Ministry spokesperson Mao Ning said on Monday.
