Cambodia's exports to the United States, the country’s biggest market, were valued at about $2.8 billion last year, a three per cent rise from $2.7 billion in 2012, according to fresh statistics from the US Department of Commerce.

Ken Ratha, a spokesman for Cambodia’s Ministry of Commerce, said exports were mainly garments, textiles and footwear, milled rice, and agricultural products.

“Our production is better and we are also focusing on the products that can sell at higher prices,” he said.

The world’s largest economy accounted for nearly 30 per cent of Cambodia’s export value last year, which stood at around $9 billion.

Hing Thoraxy, senior researcher at the Cambodia Institute for Cooperation and Peace, said that the slight growth was not a concern, and that total exports had also increased elsewhere, such as the European Union and Japan.
