Viet Nam is vulnerable to climate change, therefore Viet Nam has developed climate change (CC) policy rapidly in the last 10 years since signing United Nations Framework Convention on Climate Change (UNFCCC). Ruling political party in Vietnam realised seriously the CC challenges to set up early the direction and overall objective for CC adaptation and mitigation. This paper presented for the single case of the CC policy development in Vietnam in .highest level commitment of Vietnamese Government to international CC framework. Based on the major policy instruments such as National Target Program to Respond to Climate Change (NTP-RCC), Support Programme to Respond to Climate Change (SP-RCC), some key sector policies in energy water and disaster risk reduction, agriculture and forestry sector, the overall goal of cc policy has been implemented in Vietnam in both adaptation and mitigation. However, there are still some weaknesses in the CC policy implementation for example financial resources, institutional capacity as well as requiring more participatory and transparent in CC policy implementation.
