China is ramping up publicity for its upcoming World War II military parade, but officials still aren't saying what other countries are taking part in the spectacle.

Propaganda officials escorted foreign journalists Saturday on a tour of a military base outside Beijing, where troops are practicing for the Sept. 3 parade that will feature 12,000 soldiers and 500 pieces of military equipment.

Almost 200 aircraft are also taking part.

Reporters observed hundreds of troops in dress uniform and full battle attire engaging in eight hours of daily marching practice along a tarmac strip similar to the avenue they will march down in the heart of Beijing.

China says more than 10 countries will send contingents to join in, but has only identified Russia and Kazakhstan as being among them.
