A Chiense marine patrol ship shows a banner "Welcome Home" to Chinese nationals onboard the passenger vessel Wuzhishan as the Wuzhishan vessel heads to Haikou, capital of south China's Hainan Province, May 20, 2014. The first group of violence-stricken Chinese workers in Vietnam arrived at the port in Haikou on Tuesday morning. The Chinese government sent four vessels on Sunday to evacuate riot-stricken Chinese workers in Vietnam where severe violence targeting foreign companies since May 13 has left two Chinese nationals dead and more than 100 others injured.
