China's Hainan Airlines is expanding its network to Cambodia, with the launch of Sanya-Phnum Penh route on December 30, 2016.

The Haikou-based carrier would fly Boeing 737-800 aircraft twice weekly between Sanya and Cambodian capital Phnom Penh.

To facilitate outbound travel, the airline has opened another two chartered flights to Luang Prabang and Vientiane, Laos around the New Year.

Besides, Hainan Airlines announced it will open a chartered flight service next Wednesday connecting Sanya with Siem Reap, the gateway to Cambodia's Angkor ruins.

Hainan Airlines, the fourth largest airline in terms of fleet size in mainland China, has been operating for 23 years and has more than 160 aircraft in service.
