【明報專訊】TODAY (June 6) and tomorrow are to see in Beijing the 8th Sino-US Strategic and Economic Dialogue and the 7th Sino-US High-Level Consultation on People-to-People Exchange. President Xi Jinping is reportedly to attend the joint opening ceremony and give a speech at it. Yesterday, the 6th Sino-US Strategic Security Dialogue began. Such high-level dialogues impact greatly on the way Sino-US relations will develop. In particular, when the two countries differ vastly about the South China Sea and their armed forces have had a confrontation there, what comes of such talks will serve as indicators.
