Chinese Foreign Minister said on Saturday his country will vigorously defend its sovereignty, declaring there was "no room for compromise" with Japan over territory or history.

"We will never bully smaller countries yet we will never accept unreasonable demands from smaller countries," Wang Yi, the minister of foreign affairs, told reporters.

"On issues of territory and sovereignty, China's position is firm and clear: We will not take anything that isn't ours, but we will defend every inch of territory that belongs to us."

The dispute with Tokyo is particularly tense given historical animosities between the two countries over Japan's invasion of China in the 1930s and 40s.

Beijing and Tokyo both claim a small uninhabited archipelago in the East China Sea, administered by Japan as the Senkaku Islands, but which China calls the Diaoyu Islands.

Chinese officials and state media have this year demanded that Japan reflect on its historical aggression and atrocities, in much the same manner as postwar Germany has with its Nazi past.

"On the two issues of principle, history and territory, there is no room for compromise," Wang told reporters on the sidelines of the National People's Congress, China's Communist-controlled legislature.

"If some people in Japan insist on overturning the verdict on its past aggression I don't believe the international community and all peace loving people in the world will ever tolerate or condone that."

Tensions between the two have risen markedly since 2012 when Tokyo purchased islands in the chain it did not already own from their private Japanese owners. Beijing has taken an increasingly hard line on the issue ever since.

Ships and aircraft from both countries regularly patrol waters around the contested territory and have on occasion come perilously close to armed clashes.
