Did cambodia and laos support the viet cong?

Yes, both Cambodia and Laos provided support to the Viet Cong during the Vietnam War. The Ho Chi Minh Trail, which ran through Laos and into Cambodia, was a crucial supply route for North Vietnamese forces and the Viet Cong. Additionally, the communist sympathies in both countries facilitated the movement of troops and resources, although their governments were not officially aligned with North Vietnam. This involvement contributed to the regional complexities of the conflict.
