The European Commission's Charge d'Affairs has confirmed that the blacklisting of Siem Reap Airways from Europe was rooted in "problems with civil aviation security in Cambodia". This week, the airline had responded to the ban by claiming that the problems were mainly administrative. "There is partly a problem of registration of the aircrafts," said Rafael Dochao Moreno. He said the EC intends to work with Cambodian authorities to solve the problem.
