Why did Japan invade China

Trouble between Japan and China in the East China Sea

In the past few days, Chinese ships had been sighted several times off Japanese-controlled islands in the East China Sea. Japan's Coast Guard said there were five on Tuesday. The day before, 15 ships, including those of the Chinese coast guard, had been sighted, it said.

The Japanese government has now summoned China's ambassador to Tokyo - the second time since Friday. Foreign Minister Fumio Kishida wanted to express the sharp protest of his government, it was said from Tokyo. "We cannot accept (China) making decisions that unilaterally exacerbate tensions," said Kishida.

Sea maneuvers with missiles and torpedoes

The islands called "Senkaku" in Japan and "Diaoyu" in China are claimed by both states, but are currently controlled by Japan. According to Japanese figures, even 230 Chinese fishing boats accompanied by the coast guard entered the waters around the archipelago on Sunday. Last week, China's navy held maneuvers in the East China Sea that included rockets and torpedoes.

Years of conflict between Japan and China

Beijing has been fighting with Tokyo over the strategically important, uninhabited rocky islands for years. There are rich fishing grounds and natural resources in the area. The conflict flared up again in 2012 when the Japanese government bought three islands from private hands, sparking large anti-Japanese protests in China.

China's claims to power in the East China Sea are as controversial as those in the South China Sea. There, Beijing and several other states from the region are in dispute over various archipelagos. Experts fear that the conflict will widen even further without steps to de-escalate.
