<h1>Three major powers signal closer economic and social cooperation after summit, raising trade and security concerns</h1> Three major powers signalled a trend toward closer cooperation across economic and social policy areas after a summit, with public displays of unity prompting external commentary from a fourth state and reference to increased trade measures against one participant. The foreign ministry framed the rapprochement as driven by shared interests in development and living standards while noting differences remain. An academic source cautioned that trilateral institutionalisation is unlikely, predicting strengthened bilateral ties instead. The developments could affect regional security arrangements, economic complements within the multilateral forum, and third-party trade and sanctions dynamics.
