Cambodia's fledgling insurance industry earned a total premium of 32.2 million U.S. dollars in the first six months of 2015, up 20 percent from 26.8 million U.S. dollars a year earlier, official data showed on Monday.

The premium mainly came from fire, engineering, marine cargo, motor-vehicles, health and personal accident policies, according to the Insurance Association of Cambodia.

"The remarkable rise in the insurance revenue is thanks to better economic situation and greater inflows of foreign direct investment into Cambodia," President Huy Vatharo of the association said.

The Southeast Asian nation has eleven insurers, including eight general insurance firms and three life insurers.

Under the kingdom's law, an insurance company must have the minimum capital of 7 million U.S. dollars.
