越泰印尼去东京开会，美国突然放话加关税，这背后到底啥意思

Group 1 - Japan recently hosted a defense dialogue in Tokyo, ostensibly discussing maritime security with Pacific island nations, but also invited seven ASEAN countries, including Vietnam, Thailand, and Indonesia, which attended as observers without signing any agreements or participating in joint statements [1] - Vietnam's participation appears to align with Japan, but it has recently completed cooperation with the US and removed from the entity list, while its trade with China exceeds $70 billion more than with the US [3] - Thailand's military budget has increased by nearly 20% amid ongoing border conflicts, and Japan has pledged ¥50 billion in low-interest loans for port construction, yet Thailand remains reliant on China for practical support, such as a recent ceasefire agreement with Cambodia [3] Group 2 - Indonesia's new government faces security policy divisions, having purchased Japanese P-1 anti-submarine aircraft while receiving $1 billion in credit support from China for undersea cable construction, indicating a strategy to maximize technical support and funding from multiple sources [5] - Japan aims to expand its influence in the region through this meeting, but its economic situation is challenging, with the yen hitting a 53-year low and defense budget growth not keeping pace with inflation [5] - ASEAN countries maintain their stance that security issues should be led by ASEAN itself, reflecting a cautious approach to external influence [9][10]
