US/Taiwan - while no formal treaty exists the US has been Taiwan long time ally of the books.
The UK has the Five Power Defence Arrangements - Between United Kingdom, Australia, New Zealand, Malaysia and Singapore.
The UK also has close dense ties with Brunei.
The other grouping in the area is ASEAN - . Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam. Of the ASEAN
