TOKYO • Japan's Prime Minister Shinzo Abe sent a ritual offering to a controversial war shrine yesterday, drawing fire from China, which sees it as a painful reminder of Tokyo's warring past.

The conservative premier - who has been criticised for what some see as his revisionist take on Japan's wartime record - sent a sacred "masakaki" tree bearing his name to the Yasukuni Shrine at the start of a four-day festival.

The shrine honours millions of Japanese war dead, but also senior military and political figures convicted of war crimes after World War II.

The site has for decades been a flashpoint for criticism by countries that suffered from Japan's colonialism and aggression in the first half of the 20th century, including China and the two Koreas.

More controversial than the shrine is an accompanying museum that paints Japan as a liberator of Asia and a victim of the war.

"The Yasukuni Shrine honours Class A war criminals of WWII who were directly responsible for the war," said Chinese Foreign Ministry spokesman Hua Chunying, speaking in Beijing.

"We oppose this ritual offering and we urge Japan to reflect on its aggressive history and take concrete actions to win back the trust of its Asian neighbours and the international community."

South Korea did not immediately issue an official response.

Mr Abe and other nationalists say Yasukuni is merely a place to remember fallen soldiers and compare it with the Arlington National Cemetery in the United States.

He visited the shrine in December 2013 to mark his first year in power, a pilgrimage that sparked fury in Beijing and Seoul, and earned a diplomatic rebuke from close ally the US, which said it was "disappointed" by the action.

But Mr Abe has since refrained from going, sending ritual offerings instead.

Scores of conservative lawmakers, possibly including Cabinet ministers, are expected to visit the shrine to mark the autumn festival today.
