The Philippines and Vietnam have agreed to strengthen their coastguard cooperation to prevent incidents in the South China Sea, a move that could potentially upset Beijing. This agreement was announced during a state visit by Philippine President Ferdinand Marcos Jr. to Vietnam. The two countries have also signed a Memorandum of Understanding on Incident Prevention and Management in the South China Sea and a Memorandum on Maritime Cooperation. Furthermore, Vietnam, a significant rice exporter, has committed to a five-year trade agreement to supply white rice to the Philippines.
