知情人士称，本周初，约300名在刚果民主共和国铜矿带工作的中国公民被拘留，此举是打击非法采矿行动的一部分。
About 300 Chinese nationals working in the Democratic Republic of Congo’s copper belt were detained earlier this week as part of a crackdown on illegal mining, according to people familiar with the matter.
知情人士称，逮捕行动主要在采矿中心科尔韦齐进行，这些人要求不具名，因为这是一个敏感问题。中国公司主导着刚果的铜产量，一些知情人士称，工人因涉嫌在其他公司的采矿特许权上从事非法采矿而被捕。
The arrests took place mostly in the mining hub of Kolwezi, the people said, asking not to be named describing a sensitive issue. Chinese companies dominate copper output in Congo, and workers were arrested for their alleged involvement in illicit mining on concessions belonging to other firms, according to some of the people.
一些知情人士称，执行逮捕的官员包括刚果国家安全委员会和移民管理局的特工。中国驻金沙萨大使馆进行了干预，一些工人随后已获释，他们说。
The officials carrying out the arrests included agents from Congo’s National Security Council and immigration authority, some of the people said. The Chinese embassy in Kinshasa intervened and some of the workers have since been released, they said.
中国大使馆，以及刚果的矿业部、移民管理局和总统府均未回应置评请求。
The Chinese embassy, and Congo’s mining ministry, immigration authority and presidency didn’t respond to requests for comment.
近年来，主要由中国投资推动的浪潮助推了刚果的铜产量扩张，帮助该国自2015年以来产量翻了三番，并超越秘鲁成为世界第二大生产国。但采矿热潮也带来了混乱。
A wave of mainly Chinese investment has fueled Congo’s copper expansion in recent years, helping the nation triple output since 2015 and surpass Peru as the world’s second-largest producer. But the mining boom has also brought disorder.
