Tomorrow, Vietnam's President To Lam is expected to visit Thailand at a particularly important moment in bilateral relations. The two-day visit comes as Vietnam and Thailand commemorate the 50th anniversary of diplomatic ties, which is a milestone that reflects not only the remarkable transformation of bilateral relations but also the increasing strategic relevance of the partnership as the Association of Southeast Asian Nations (Asean) navigates heightened great-power rivalry, regional instability, and emerging non-traditional security challenges.
Few relationships in Southeast Asia have evolved as dramatically as that between Vietnam and Thailand. Once divided by Cold War tensions and opposing geopolitical alignments, the two countries have gradually transformed their relationship into one of Asean's most dynamic and substantive bilateral partnerships.
