On February 27, 2025, the Hanoi People’s Court sentenced journalist and author Truong Huy San — also known by his pen name Osin Huy Duc — to 30 months in prison for “abusing democratic freedoms to infringe upon the interests of the State, the legitimate rights and interests of organizations and individuals,” as stipulated in Article 331, Clause 2 of Vietnam’s Penal Code. 

The court found that between 2015 and 2024, Truong Huy San independently collected information and published numerous articles on his personal Facebook account, “Truong Huy San (Osin Huy Duc).” Thirteen of these posts were found to contain content that infringed upon state interests and the legitimate rights of various organizations and individuals. These posts garnered significant interaction, comments, and shares, negatively affecting national security, public order, and social safety.
