Prime Minister Hun Sen got an unexpected send-off from thousands of striking garment factory workers Thursday morning when his motorcade passed the marchers along Russian Boulevard as he traveled to Phnom Penh International Airport to depart for a three-day state visit to Vietnam. Holding paper placards demanding a salary of $160 per month, many among a crowd of between 5,000 and 6,000 garment workers chanted “Hun Sen Euy! Choh Chenh Tov! [Hun Sen get out],” as the prime minister’s car and an accompanying entourage of senior government officials passed by the marchers.
