At Tuesday’s opening ceremony, Caitlin Wiesen, UNDP Country Director in Vietnam, called for practical activities like saying no to single-use plastic products to create a greener, cleaner Vietnam.

Themed “Save our seas”, the 5-day exhibition is showcasing 100 photos to raise people’s awareness about plastic waste, suggest feasible solutions, and urge Vietnam’s ministries, agencies, enterprises, and people to reduce plastic pollution in Vietnam.
