During his speech, Kishida also spoke about Japan’s planned efforts to strengthen nations in the Indo-Pacific both in security and economic aspects. The security side will include transferring patrol boats in the region, strengthening regional maritime law enforcement capabilities (emphasis applied–Chuck) and providing defense equipment and technology transfers. Singapore is one of the countries that will sign a defense equipment and technology transfer agreement with Japan.
As China has become more agressive in its behavior, Japan has been a lot more active in reaching out to help friendly nations. It appears they have decided to provide an Asian nation alternative to Chinese hegemony. One of the ways they have done this is transfer of vessels to conduct coast guard functions on favorable terms. We have already seen this with the Philippines (and here), Indonesia, Malaysia, and Vietnam.
We have also seen increased interaction between the Japan Coast Guard and the USCG here, here, here, and here. Japan seems to be promoting coast guards as a way to maintain rules based international norms and may be looking to create an international consensus on coast guard behavior to promote cooperation and interoperability. They are looking at their own Coast Guard’s role as well. They seem to be looking to the USCG as an allied, internationally recognized example of proper coast guard functions to help achieve this consensus.
