China imposed temporary controls on retail prices of gasoline and diesel today as global oil prices climb, the country's top economic planner said. While prices were set to rise by over CNY2,100 (USD304) per ton, actual increases will be capped at about CNY1,160 for gasoline and CNY1,115 for diesel, saving drivers around CNY40 to CNY50 (USD5.79 to USD7.24) per tank.
