A Chinese official and scholars issued an alert over right-wingers in Japan on Sunday following Japanese Prime Minister Shinzo Abe's offering of a ritual donation to a shrine endorsing convicted war criminals.

On Saturday - the 70th anniversary of the end of World War II - some Japanese Cabinet members and about 70 lawmakers visited the Yasukuni Shrine in Tokyo.

Abe's ritual offering was conveyed by an official from the ruling Liberal Democratic Party.
