The first quarter's pace compares with a decline of 2.8% in the previous quarter. On a quarterly basis, the economy grew a revised seasonally adjusted 5.4% for the January-March period, up from a 0.5% growth in the previous quarter.

The government also maintained the real GDP forecast for 2021 as a whole of 3.5% to 5.5% growth.

"Yet, the actual outturn can hopefully be near the upper end of the range forecast if the pandemic situation improves in the period ahead," the government said in a statement.
