The government handed a New Year's Eve shock to Colombian motorists Monday, announcing that domestic gasoline prices would go up by 22 percent Jan. 1.

Mines and Energy Minister Luis Fernando Vergara said the government had decided to raise prices by 22 percent - the same figure that the government had set as its goal for inflation in 1991. Colombian inflation is currently running at just over 30 percent per year.The increase applies to gasoline, propane gas and other oil-derived fuels. Vergara said the increase should not cause more than a 1.1 percent rise in overall cost of living in 1991.
