The capital-labor conflict is one of major risks to be faced with by Chinese firms that develop overseas. Taking CNMC’S experience in Zambia as an example，this paper analyzed the multiple reasons that led to the frequent occurrence of capital-labor conflict from the perspective of game relationships among Chinese investor，local labor and Zambia’s major parties. The frequent occurrence of capital-labor conflict not only has to do with employment practice and management styles taken by Chinese company，but also with work moral and protest tradition held by Zambia miners. However，party politics in Zambia is another important factor that affects the relationship between Chinese investor and local miners. In order to get the vote support from miners，the opposition party brought the topic about industrial relations into Presidential election competition，which stimulated the protests against Chinese capital from the local miners. Therefore，Chinese overseas investors not only pay attention to undertake social responsibilities in host countries，but also learn to safeguard their own rights and interests in the democracy of party competition.
