This is a short introduction for an essay about ASEAN. I was wondering if the sentences flow smoothly and read well. I hope you could give specific criticisms regarding the essay. Thanks!

“The different cultural and political identities of Southeast Asian countries result in their disunity. Understandably, these countries, being former colonies, are reluctant to enter into binding agreements with each other, much less create strong supranational institutions, since doing so might adversely affect their hard-won sovereignty. Non-interference is, therefore, a staple policy in the way they conduct their relations with each other, believing that such is necessary to respect their vast differences. This policy breeds weak monitoring and enforcement mechanisms as well as indifference within the community. Just consider the continuing human rights violations in Myanmar or the on-going territorial disputes in the region which the ASEAN consistently fails to address. What makes these countries even more distant from each other is the presence of different international organizations in Asia-Pacific which encourages them to forum shop rather than to strengthen their commitments to ASEAN."
