The event is co-organized by the Ho Chi Minh Communist Youth Union and the Lao People Revolutionary Youth Union.
Speaking at the launching ceremony, Vietnamese National Assembly Vice Chairwoman Tong Thi Phong expressed the belief that the young generations of Laos and Vietnam will continue to strengthen and develop the bilateral relations.
The young people then joined hands to paint a 55 meter-long picture marking the 55th anniversary of Vietnam-Laos diplomatic relations.
An exhibition of 150 photos honoring the relationship between the two countries was also opened on the same day.
Leaders of both youth unions participated in a discussion on building a traditional museum on histories and national leaders of Laos and Vietnam, and publishing books on national revolutionary leaders of the two countries.
