The composition of imports changed little in 2010 compared with 2009. Petroleum and crude oil was the main import commodity, comprising 13.6% of total imports, up from 12.7% in 2009. Natural gas imports comprised 2.6% of total imports in 2010, down from 3.5% in 2009. Wheat imports rose to US$171.7m in 2010, equivalent to 3.4% of total imports, up from 2.4% in 2009. This is likely to reflect higher world prices for wheat during the second half of 2010, rather than a substantial increase in the amount of wheat imported (December 2010, Foreign trade and payments).
