In her book “Is International Law International?”, Anthea Roberts raises the concept of “comparative international law”. Roberts illustrates the different national and regional approaches towards understanding, interpretation and application of international law. She points out that national approaches to international law plays an important part in “a transnational field that aspires to develop common rules to facilitate inter-state coexistence and cooperation”. Furthermore, academics play an influential role in a State’s international law practice, through their scholarship and practice.
The approach of comparative international law is useful in the Polar Regions. In recent years, China has been significantly expanding its presence in Antarctica. For example, China now operates three research stations in the Australian Antarctic Territory (AAT), including Kunlun Station at Dome A – the highest point of the Antarctic ice sheet, and since 2013, China has been proposing to establish an Antarctic Specially Managed Area around Kunlun Station to the Antarctic Treaty Consultative Meetings. Furthermore, China is now building its fifth Antarctic station on Inexpressible Island in the Terra Nova Bay of the Ross Sea.
