Abstract: As the American hegemony declines, globalization and regional integration have gained momentum, and international regimes of different levels have undertaken the main responsibility of supplying the global public goods. Regional public goods, as a supplement to global public goods in the region, plays an Important role. It either competes with global public goods or complements it. In terms of Northeast Asia marine environment governance, the two regimes have some differences in principles and norms. In this sense, the supply of public goods tends to follow a pathway in which the two levels of governance complement each other. In this mutually complementary multi-level way of supply, under the principles of correspondence and subsidiarity, the two different regimes interact in a positive way, which could be regarded as an effective method to tackle the inefficiency of public goods supply.

Key words: Northeast Asia marine environment governance, regional public goods, complementarity, principle of correspondence, principle of subsidiarity
