Vietnam's trade surplus in the first quarter of this year was the highest since 2010, dpa cited government figures as showing. Exports in the first quarter rose 14.1 per cent from the same period last year to 33.3 billion dollars, while imports were up 12.4 per cent to 32.3 billion dollars, the General Statistics Office (GSO) said. The resulting 1-billion-dollar surplus was the highest quarterly figure for any quarter in the last four years. Vietnam's gross domestic product rose 4.96 per cent year-on-year in the first quarter, the highest growth in three years, GSO said. The government, which measures the first quarter up to March 25, has set a target of 5.98 per cent growth this year
