East Sea 2020 - From diplomatic note to the rule of law

The year 2020 has seen many countries become more outspoken about the East Sea (known internationally as the South China Sea) through diplomatic notes exchanged at the UN.

Not only countries in the region, but many outside the region have spoken up as members of the 1982 UN Convention on the Law of the Sea (UNCLOS).

The East Sea is not simply a matter between ASEAN and China but a matter of international concern.

The world has witnessed a "war of diplomatic notes" related to the East Sea starting with Malaysia's submission to the UN Commission on the Limits of the Continental Shelf last December information on the limits of its continental shelf beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured. Subsequently, many other countries sent notes and letters protesting China's actions in the East Sea.

Note diplomacy

In September, Britain, France, and Germany sent notes to the UN expressing their common view on the East Sea, emphasizing UNCLOS 1982 as establishing a legal framework for maritime activities worldwide. Jointly supporting freedom of navigation and overflight in the East Sea, the note is specific about the right of innocent passage through territorial waters.

The Philippines, Vietnam, Indonesia, the US, and Australia all sent notes opposing China's arguments. To date, there have been more than 20 diplomatic notes and statements from countries all over the world.

The notes condemned China's claims, saying the so-called "9-dashed line" is contrary to international law and UNCLOS. They affirmed that UNCLOS is an important legal document, which plays a fundamental role in solving maritime problems and that the 2016 Permanent Court of Arbitration (PCA) ruling is an important part of international law and UNCLOS that China should respect.

Towards East Sea security and safety

The use of notes shows that countries have focused on international law, especially UNCLOS as a basis to settle disputes rather than taking actions that may trigger confrontation or a military conflict.

The East Sea issue has been addressed frequently at regional and global forums: the ASEAN Regional Forum (ARF), the East Asia Summit (EAS), the ASEAN Defense Minister Meeting (ADMM), and the ASEAN Defense Minister Meeting Plus (ADMM +) to the G20 Summit and the Asia-Europe Cooperation Forum (ASEM).

All countries desire peace, stability, security, safety, freedom of navigation and overflight, non-militarization, and restraint from complications and tensions, and peaceful settlement of disputes in accordance with international law including UNCLOS. Countries support full and effective implementation of the 2002 Declaration of Conduct of Parties in the East Sea  (DOC) and early completion of an effective Code of Conduct in the East Sea (COC).

A safe, secure and prosperous East Sea is what countries are aiming for. Recent developments suggest that the world can hope for a more peaceful and stable East Sea in 2021.
