Over the week, copper at the LME rose by around 1.5%, while prices in Shanghai increased by around 1%

Asian equities were poised for a strong week on a milder note, as the euphoria over trade negotiations between the United States and China faded, while renewed bets on an easing of US policy triggered a rally in troubled bond markets
