An American student arrested in Vietnam during an anti-China protest earlier this month apologized on state television for breaking the law and promised not to participate in further “anti-state activities,” Agence France-Presse reports. Will Nguyen, a 32-year-old graduate student in Singapore, has been detained since June 10 when plain-clothed officers beat and dragged him through the streets amid an anti-China protest in Ho Chi Minh City. “I regret that I caused trouble for people heading to the airport,” Nguyen said in Vietnamese in the televised statement, AFP reports.
