South China Sea, Sea in Southeast Asia.
It stretches between Southeast Asia and the Philippines across warm tropical waters, broken by numerous islands, reefs, and shallow banks. The sea connects the coasts of Vietnam, China, the Philippines, Malaysia, Brunei, and Indonesia through open waterways and shallow continental shelves.
Chinese merchant vessels transported silk and porcelain through these waters to ports across Asia since the Han Dynasty. European powers controlled key passages for the spice trade between Asia and Europe from the 16th century onward.
Fishing boats with painted hulls and traditional sails still work the coastal waters, where families have lived from the sea for generations. In Vietnamese coastal villages, vendors bring the daily catch straight to markets, where locals prepare fresh seafood using time-honored methods.
Coastal areas along the Vietnamese side offer access to beaches, harbors, and small islands reachable by boat. Water temperatures remain warm year-round, with weather conditions becoming rougher during monsoon season from May through November.
Water in certain areas glows at night with bioluminescence, caused by microorganisms that produce greenish blue light when disturbed. Local fishermen sometimes use this effect to locate schools of fish that cause the water to light up as they swim.
