China announced tariff exemptions for a basket of US goods, a move viewed by many investors as a show of good faith just weeks ahead of planned talks aimed at resolving the trade war, which has bruised world economies and rattled markets for months.

Markets still expect the Fed to cut interest rates by 25 basis points at the conclusion of its monetary policy meeting next week.
