Tran Yaing Chang, 32, speaks with Reuters during an interview at her house in Phnom Penh March 11, 2014. Her brother, 30-year-old carpenter Tran Van Chien, was standing among onlookers on February 16 following a minor road accident when someone shouted "yuon," a term widely seen as derogatory to the hundreds of thousands of ethnic Vietnamese who call Cambodia home. Seconds later, the crowd turned on him and killed him. For centuries Cambodia was caught between more powerful Thai and Vietnamese kingdoms and for generations, many Cambodians have believed Vietnam wants to take over their land. At various times, Cambodian politicians have found it useful to play up that fear. Recently, the resurgent opposition Cambodia National Rescue Party (CNRP) has stoked anti-Vietnamese sentiment, seeking to capitalise on long-ruling Prime Minister Hun Sen's association with Vietnam.
