Hong Kong's exports increased 11.9 percent in the first quarter of this year compared to the same period last year, according to official figures released on Thursday.

Despite a slight decline in February, exports picked up 4.7 percent in March on a year-on-year basis, resulting in an overall surge for the quarter.

Exports to Thailand saw the largest expansion, followed by those to the United Arab Emirates and the mainland, while shipments to the Netherlands dropped in the first three months of the year.

Meanwhile, imports saw 8 percent year-on-year growth in the quarter.

In a statement, a government spokesperson said uncertainty remains in the city's exports performance.

"Looking ahead, geopolitical tensions and a longer period of tight financial conditions will continue to affect Hong Kong's export performance, though the slightly better-than-expected external demand may provide some support," the spokesperson said.
