Juan Ordonez Camacho, 50, was arrested in the southern seaside town of Sihanoukville in January and accused of sexually abusing the teenager on numerous occasions in 2010, the victim’s lawyer Nuon Phanit told AFP.
Preah Sihanouk provincial court ordered Camacho to be deported after serving his jail term, he added.
“We are satisfied with the conviction. The court has provided justice for my client,” Nuon Phanit said.
Cambodia launched an anti-paedophilia push in 2003 to try to shake off its reputation as a sex predators’ haven. Dozens of foreigners have since been jailed for child sex crimes or deported to face trial in their home countries.
