debatable, Indonesia’s proactive initiatives to address regional problems reflect its
capacity to effectively lead the region. Under the Chairmanship of Indonesia in 2023, the
5-PC were reviewed and additional decisions were taken including urging “Myanmar
Armed Forces in particular, and all related parties concerned in Myanmar to de-escalate
violence and stop targeted attacks on civilians, houses and public facilities, such as
schools, hospitals, markets, churches and monasteries” and mobilising “further support
from External Partners and the International Community to ASEAN efforts on
humanitarian assistance” (ASEAN, 2023a, para. 11& 17).
However, to properly weigh the extent of influence Indonesia possesses within ASEAN, it
is important to look into the effect of internal fragmentation of the organisation. For
instance, only Cambodia, Laos, Thailand and Vietnam hold bilateral ties with Myanmar,
while the rest of the ASEAN members do not. The varying individual interests have the
potential to weaken the regional cohesion. In June 2021, divisions within ASEAN became
apparent when several members abstained from voting on a UN General Assembly
resolution concerning the deteriorating political atmosphere of Myanmar. The resolution
appreciated ASEAN’s adoption of the 5-PC and urged its swift implementation while
condemning the violence inflicted upon the peaceful demonstrators and calling for an end
to the same. Although six ASEAN members voted in favour, Brunei, Cambodia, Laos, and
Thailand abstained from voting. Samet (2021) observes that the draft resolution was
strongly worded and included a call for a global arms embargo, which has been omitted
in the final resolution. It was the Southeast Asian states that had requested, through a
letter, to soften the language in order “to make the text acceptable”. Hence, the
divergence in positions reflects how national economic interests outweigh collective
action. As a result, ASEAN is bound to adopt diluted measures to ensure consensus,
avoiding harsher steps such as an arms embargo. While this makes the outcome
acceptable to all members, it hurts the effectiveness of the action plans.
Another major concern for Southeast Asia is the South China dispute, which dates back
to the 1970s. Article 47 of the United Nations Convention on the Law of the Sea (1982)
states that the Exclusive Economic Zone (EEZ) shall not extend beyond 200 nautical
miles from the baselines from which the breadth of the territorial sea is measured. As
per Article 56 of UNCLOS (1982), the coastal state has sovereign right of exploring,
exploiting, conserving, and managing the natural marine resources located within the
exclusive economic zone, among other rights. China, drawing on its historical territories,
claims beyond this internationally set limit. The area claimed by China in the South China
Sea overlaps with the EEZ of several ASEAN member states and is termed the “Nine-
dash Line”. In the 1970s, China militarily seized 3 islands beyond its EEZ (Putra, 2015).
This military activity was a direct encroachment on the international maritime rights of
the neighbouring Southeast Asian Countries, including Brunei, the Philippines, Vietnam,
Malaysia and also Indonesia, with respect to the Natuna Islands. Subsequently, the
Declaration on the Conduct of Parties in the South China Sea (DOC) was signed between
ASEAN members and the government of the People’s Republic of China on 4th November
2002. The declaration reaffirmed the commitment to principles of the Charter of the
United Nations, the UNCLOS, and other universally accepted principles of international
law. The declaration also emphasised resolving their territorial and jurisdictional disputes
by peaceful means and not through threat or use of force (ASEAN, 2012).
