China Southern Airlines, the country's biggest airline, opened direct flights from Guangzhou, capital of southern Guangdong Province, to Siem Reap in Cambodia on July 12.

The company also runs direct flights from Guangzhou to Phnom Penh, the Cambodian capital.

Earlier in July, China Southern set up three new routes linking Guangzhou with Myanmar's capital Yangon, Phuket in Thailand and Laos' capital city Vientiane.

The airline intends to open direct flights from Guangzhou to Delhi in September.
