Dubai Telegraph - China and Japan's long history of strained ties

Here are some of the key issues that have long impacted the relationship between Asia's two biggest economies:

- Historical wars -

Japan's early 20th-century imperial ambitions resulted in occupations across Southeast Asia and East Asia, including China.

Atrocities after its invasion of China in the 1930s include the "Rape of Nanking" -- a period of mass murder and rape committed after Japanese soldiers took the city -- as well as torture, sexual slavery and human medical experiments.

The Sino-Japanese War, part of World War II, ended with Japanese military defeat in 1945.

Ties were restored with a 1972 Joint Communique in which China renounced "its demand for war reparation from Japan" to foster links between the two countries.

But history remains a stumbling block in modern diplomacy, especially as the two tussle over regional influence.

Over 10,000 people protested in Beijing after Tokyo approved revisionist textbooks in 2005, hurling rocks and eggs at the Japanese embassy.

Old wounds also resurface when nationalist Japanese politicians visit Tokyo's Yasukuni Shrine -- which commemorates senior military and political figures convicted of war crimes after WWII.

China terms these visits as "serious provocations", urging Tokyo to "learn from history".

"The Japanese have been their own worst enemies on history issues," said East Asia analyst Richard McGregor.

But this is due to the Japanese government's belief that China would never accept an apology and "politicise the issue no matter what," he added.

- Territorial disputes -

Another point of contention has been a territorial dispute over islets in the East China Sea, known as Senkaku by Tokyo and the Diaoyu by Beijing.

The remote chain of islands has long fuelled tensions and is the scene of regular confrontations between Japanese coastguard vessels and Chinese fishing boats.

Beijing has grown more assertive about its claim over the islands in recent years, with Tokyo reporting the presence of Chinese coastguard vessels, a naval ship and even a nuclear-powered submarine.

Japanese Prime Minister Fumio Kishida said he had "expressed serious concerns over the situation in the East China Sea" to Chinese President Xi Jinping during the pair's first in-person talks in Bangkok last year.

- Alliances -

The United States has been a staunch ally of Japan since the end of World War II.

Japan hosts several US military bases, with the southernmost region of Okinawa containing the bulk of the 50,000-strong troop presence -- right at the doorstep of mainland China.

This has fuelled China's belief that the United States is intent on encircling and containing it.

But as Beijing's sabre-rattling around Asia grows more frequent, Tokyo has shifted towards a more hawkish stance over security issues.

"They simply do not trust China," McGregor said.

The neighbours maintain several hundred billion dollars in economic trade annually.

But Japan has in recent years deepened its relationship with Washington -- including through the Quad alliance involving Australia, India and the United States.

"The tone of (China's) diplomatic relations with Japan is to some degree set by their relations with the United States," McGregor said.

"It's hard to see how (Japan-China) relations can bounce back in any substantial form."

- Taiwan -

Another flashpoint issue is self-ruled Taiwan -- which Beijing claims as its territory and has vowed to take one day, by force if necessary.

China has in the past year staged wargames around the island -- ruled by Japan for half a century until 1945 -- including missile drills.

Some missiles fired during Chinese exercises last August were believed to have fallen within Japan's exclusive economic zone.

While Japan recognises Beijing's "One China" policy on Taiwan, it is concerned about its neighbour's more aggressive military posture.

"Japan is exceptionally worried about what's happening in Taiwan and that's a big driver of just about everything in the region nowadays," McGregor told AFP, adding that Taipei and Tokyo share close relations.
