To build positive relationships in the region to promote wellbeing and security.
To build respect for the cultural, religious and social values of ASEAN members.
ASEAN is working to facilitate a South China Sea code of conduct that is legally binding to have China comply with regulations and punished for breaching such.
China exercised its diplomatic and economic power over Cambodia to avoid any criticism of China by ASEAN.
In 2016, Cambodia was the chair of ASEAN, and it did not allow any discussion of a proposed statement by ASEAN that would have been critical of China's incursions into the waters of the Philippines, which was the basis of the court decision.
This has, subsequently, granted China a de facto vote at ASEAN, despite being a non-member state, whereby Cambodia has been able to block statements which set precedent for China’s ‘unlawful’ acts in the South China Sea.
In this way, they have also been able to solidify their legitimacy of security control in the waterways.
Given that decisions of ASEAN must be unanimous, China only needs the votes of one or two states, Cambodia and Laos, to be able to influence ASEAN in its work.
This weakens ASEAN’s effectiveness as a regional grouping where it cannot defend the interests of its member states in times of crisis, such as in the South China Sea.
