Voice of America press release, 16 August 2010
: "VOA's Khmer Service is marking its 55th anniversary, with veteran broadcasters recalling the monumental events that shaped the news in those years, from the Vietnam War, to the genocide of the Khmer Rouge regime and the birth of a constitutional monarchy. Khen Chen, who retired in 2007, says of her 45-year career, 'I'm very proud of working for VOA Khmer, there was something new every day, it was a blessing.' ... Chen was a student at an all-girls high school in Phnom Penh, Cambodia when she spotted a job advertisement for Voice of America in 1962 and began a life-long career broadcasting to her homeland."
The Phnom Penh Post, 27 August 2010, Peter Olszewski: "The massive Bakong Technical College project to be built in Siem Reap has finally received approval from Apsara for some of its construction. Meanwhile, the project’s founder, US-based Ronnie Yimsut, is celebrating the 55th anniversary of Voice of America Khmer radio for a special reason. The radio service’s legendary Madam Ang Khen, one of the first staff to sign on back in the US in 1962, returned briefly to the airwaves this month. This especially delighted Ronnie because Madam Ang Khen is his foster mum."
