This study assesses China's approach to the global commons, those areas of the globe over which no state exercises sovereignty and that are accessible to all. Examining Chinese behaviour, official statements and expert positions towards the extant high seas and outer space regimes, this research concludes that China approaches the principle of international access to the two domains situationally, reflecting its assessment of how these regimes affect its national interests. The finding cautions against blanket characterizations of China's strategic orientation towards the global commons.
