A Vietnamese-American and two Vietnamese nationals will be put on trial on charges of terrorism for allegedly planning to distribute anti-government pamphlets in Vietnam, an official said Thursday.

Nguyen Quoc Quan, of Sacramento, and Vietnamese nationals Nguyen Hai and Nguyen The Vu face jail terms of up to seven years if convicted. Their trial begins Tuesday at the People's Court in Ho Chi Minh City, Foreign Ministry spokesman Le Dung said.

The three were arrested last November at a house in Ho Chi Minh City along with Truong Van Ba, an American, and Nguyen Thi Thanh Van, a French national. Authorities allegedly found them preparing to circulate anti-government pamphlets on behalf of Viet Tan, a California-based pro-democracy group that Vietnam considers a terrorist organization.

Viet Tan says it promotes nonviolent political change in Vietnam, and U.S. Ambassador Michael Michalak has said he has seen no evidence the group is engaged in terrorism.

Ba, whose American name is Leon Truong, and Van were released in December.

Vietnamese authorities have said Quan entered the country on a forged Cambodian passport.

Communist Vietnam does not tolerate any form of dissent, which it considers a threat against its one-party rule.
