China weakens yuan midpoint by most in two weeks

SHANGHAI, July 4 (Reuters) - China's central bank set the yuan midpoint fixing at 6.7889 per dollar on Tuesday, weakening it by 117 pips or 0.17 percent from the previous day's fix at 6.7772.

The move was its biggest one-day weakening in percentage terms since June 20.

The weakness in the yuan fixing followed a rise in the U.S. dollar overnight in the global markets. (Reporting by Winni Zhou and Andrew Galbraith; Editing by Sam Holmes)
