The statistics office has predicted that the trade deficit in May would rise sharply to US$700 million.
Exports were estimated at US$9.1 billion, up 1.5 percent and imports at US$9.8 billion, up 9.4 percent over April.
However, the trade deficit in the first five months of 2012 is just one tenth of the figure recorded in the same period last year.
