Emirates is to provide a UK connection to Cambodia via Dubai and Myanmar from the summer.
The start of daily Boeing 777-300 services from Dubai to Phnom Penh on July 1 will coincide with the introduction of a non-stop route between Dubai and Hanoi.
Emirates passengers travelling to Hanoi will no longer stop in Yangon in Myanmar before reaching the Vietnamese capital.
The new Dubai-Yangon-Phnom Penh route will enable passengers from Yangon to travel to Phnom Penh and vice versa.
Emirates will be the only airline with a direct service between the two cities.
Phnom Penh acts as a gateway to World Heritage Site Angkor Wat, near Siem Reap.
The departure time from Dubai at 9.15am allows connections with a number of European services such as Paris, London and Frankfurt.
Around 156,000 British travellers visited Cambodia in 2016, according to latest Foreign and Commonwealth Office figures.
UK visitor numbers to Cambodia have more than doubled between 2006 and 2015 and rose by 16% between 2014 and 2015.
The figure of than 4.7 million overall foreign tourist arrivals to Cambodia in 2015 is forecast to rise to 8 million by 2020.
The opening of a terminal extension at Phnom Penh airport almost a year ago will complement this growth, effectively doubling passenger capacity.
