Zimbabwe's economy is on course to grow by 9.3 percent in 2011 due to a recovery in the key mining and agriculture sectors but wage increases for state workers will be a drag on the public purse, Reuters quoted Finance Minister Tendai Biti as saying on Tuesday. The southern African country's economy grew by 8.1 percent in 2010, after a sharp contraction for most of the last decade, which critics blamed on economic mismanagement by the government of President Robert Mugabe. Biti said political problems in Zimbabwe would stop the country from registering the double-digit growth needed for a full recovery. "We are still on course to achieve our GDP growth rate of 9.3 percent. Agriculture and mining, with 19.3 percent and 44 percent growth respectively, are at the epicentre of this growth," Biti said in a half-year budget review statement. -- SPA
