【明報專訊】THE meeting and working dinner held between Chinese president Xi Jinping and US president Donald Trump, accompanied by their respective teams, in Buenos Aires lasted for more than two hours, and the outcome has been even more fruitful than that of the G20 summit. Though the meeting has brought about little more than a three-month truce when it comes to the trade war, it has prevented the escalation of the conflicts between China and US and recreated an atmosphere of both nations willing to solve the problems through negotiations. All this has influenced relations between the two countries and the global economic situation very positively. Though the deep-seated, structural conflicts between the two countries remain unresolved, the two countries can at least trade time for space, giving themselves room for manoeuvre. With China making substantive concessions, the US has saved its face, while China has won precious time for further reform with the easing of pressure from abroad.
