The global economy is not doing so well, and the value of Thai exports has fallen sharply, General Chatchai Sarikulya told reporters.
The Commerce Ministry is due to release customs-cleared trade data on Thursday. A Reuters poll of economists forecast a drop of 3.24 percent in February exports, in a further blow to the government's efforts to spur the sluggish economy.
In January, exports fell 3.46 percent year-on-year.
