In Vietnam, Hoang Thi Minh Hong, a well-known environmental activist, was arrested by police who accused her of tax evasion. Accusations rejected by his supporters who denounce a political maneuver.

Vietnam is aiming for carbon neutrality by 2050, a goal encouraged in December by a group of wealthy countries and international institutions. Several NGOs denounced in October the country's efforts to combat the effects of climate change, to which it is particularly vulnerable. The Vietnamese government reaffirmed its commitment to environmental protection and said that all associations must comply with the law.
