中国严格的资本管制限制个人每年向境外转移资金的额度为 50,000 美元，在对国家经济前景以及 President Xi Jinping 旨在减少不平等的推动的担忧下，这引发了空前的资本外逃。根据国际金融协会的估计，去年家庭、公司和机构从中国转移了创纪录的 807 亿美元资金。这种财富的快速累积和对境外资产的需求催生了庞大的地下产业以规避这些限制，从而引起了监管机构的严格审查，并导致对试图监控跨境资本流动的境外经纪商进行重大打击。
几种非法方法被用来将资金转移到境外，范围从实体现金走私到复杂的银行计划。例如，当局在 2024 年逮捕了一名携带 330,000 港元（42,000 美元）的旅客，而「拆单分拆」（smurfing）网络则利用个人配额，例如在 2020 年的一个案例中，102 名被招募的个人转移了 680 万加元（500 万美元）。此外，非正式的「镜像转帐」或地下银行以巨大规模运作；甘肃省当局拆除了一个管理著 756 亿元人民币（112 亿美元）资产的网络，国际执法部门经常将这些网络与犯罪洗钱联系在一起。
其他复杂的技术包括贸易高报或欺诈性发票以及数位资产。温州和深圳的公司分别透过虚构进口贸易转移了 900 万美元和 1,800 万美元，而退款计划在 2014 年监管打击之前历史性地利用了澳门的高价值零售取消交易。尽管中国全面禁止加密货币交易和挖矿，但区块链分析估计，中文洗钱网络在 2025 年处理了约 161 亿美元的非法加密货币交易，这表明数位资产仍然是资本外逃的主要工具。
China's strict capital controls, which restrict individuals to an annual overseas transfer limit of $50,000, have driven unprecedented capital flight amid concerns over the nation's economic outlook and policies aiming to reduce inequality. According to the Institute of International Finance, households, companies, and institutions moved a record estimate of $807 billion out of China last year. This rapid wealth accumulation and demand for foreign assets have fostered a sprawling underground industry to bypass these limits, drawing intense regulatory scrutiny and leading to major crackdowns on overseas brokers attempting to monitor cross-border capital flows.
Several illicit methods are used to move funds offshore, ranging from physical cash smuggling to complex banking schemes. For instance, authorities arrested a traveler carrying HK$330,000 ($42,000) in 2024, while "smurfing" networks exploit individual quotas, such as a 2020 case where 102 recruited individuals transferred C$6.8 million ($5 million). Furthermore, informal "mirror transfers" or underground banking operate on a massive scale; Gansu province authorities dismantled one network managing 75.6 billion yuan ($11.2 billion) in assets, which are frequently linked by international law enforcement to criminal money laundering.
Other sophisticated techniques include trade misinvoicing and digital assets. Wenzhou and Shenzhen firms fabricated trade imports to transfer $9 million and $18 million, respectively, while refund schemes historically exploited high-value retail cancellations in Macau prior to a 2014 regulatory crackdown. Despite China's total ban on cryptocurrency transactions and mining, blockchain analytics estimate that Chinese-language money-laundering networks processed approximately $16.1 billion in illicit cryptocurrency transactions in 2025, demonstrating the persistence of digital assets as a primary vehicle for capital flight.
