China is keeping mum on which foreign country's militaries it has invited to join a parade marking the end of World War II.

The Sept. 3 event will include a speech and troop inspection by President Xi Jinping, who also heads China's armed forces. War veterans and their descendants will also receive medals marking the 70th anniversary of victory in what China calls the Chinese People's War of Resistance Against Japanese Aggression.

Parade organizers at a news conference on Tuesday declined to offer details about foreign participation.

Chinese forces under then-President Chiang Kai-shek battled Japanese invaders virtually alone from 1937 until the U.S. entry into the war in 1941. Chiang's forces were later defeated by the communists in the civil war that resumed after the allies' victory in 1945.
