One of China’s biggest state-owned lenders has suspended an account used to fund ethnic rebels fighting government troops in Myanmar, halting an arrangement that could have stoked diplomatic tensions between Beijing and Myanmar. The Myanmar National Democratic Alliance Army, which clashed with government forces this month, said the Agricultural Bank Of China was no longer accepting funds into an account it used to receive donations from supporters. Reuters was unable to confirm what prompted the bank’s move. It came after Reuters sent the lender a list of questions regarding the transactions, which compliance experts said could point to a weakness in controls aimed at stopping the global financial system being used to fund terrorism or facilitate crime. The bank declined to comment on specific questions about the alliance army account, citing client confidentiality. It said in a statement that it paid high attention to anti-money laundering and counterterrorist financing work, and “diligently obeyed relevant laws, regulations and regulatory requirements”. There is no evidence that the bank or other financial entities that handled transactions for the rebel troops, have broken Chinese law. 30 dead as intense fighting breaks out in Myanmar-China border town The Myanmar National Democratic Alliance Army is not designated as a terrorist organisation by any government or transnational body. Still, several compliance experts said acceptance of the group’s funds could leave the bank exposed to questionable or potentially illegal activities. The alliance army has refused to disarm or play an active part in Myanmar’s peace process and defence analysts say it continues to acquire weapons. Its leader, Peng Jiasheng, has been identified as a major drugs trafficker by the US Drug Enforcement Agency, according to US diplomatic cables, dated 2009, released by Wikileaks. Yan Zhen Kun, an alliance army representative who oversees donations for the group, said he was informed by the bank of the account shutdown over the weekend. “We were told by the bank that we need to finalise some procedures,” he said. “It did not tell us how long this might take.” The alliance army’s forces attacked troops in northeastern Myanmar this month, sending more than 20,000 people fleeing across the border to China. It said it was responding to “continued military pressure” from the army. Myanmar says it accepts Beijing’s assurances it is not supporting the rebels. Zaw Htay, director general of Myanmar leader Aung San Suu Kyi’s office, said Myanmar was “fully convinced” by assurances from China’s leadership that it was not backing ethnic armed groups on the border. Still, Myanmar had complained to Beijing about low-level Chinese officials it believed were helping the rebels for their own gain, he said. Records on the alliance army’s website show it collected more than half a million dollars over nearly two years after making a “crowdfunding” appeal for donations. Donors either deposited the money directly in an Agricultural Bank account or sent it via two mobile payment services - Tencent Holdings’ WeChat Pay and Alipay, part of Ant Financial, which is affiliated with US-listed Chinese e-commerce giant Alibaba. Ant Financial declined to comment specifically on Reuters’ questions about the alliance army’s use of its Alipay platform, but said it was investing a lot in risk management. “There are a lot of bad actors out there who try to take advantage of these accounts so we’ve built a pretty good system at detecting those early and then enabling ourselves and our partners to stop transactions,” said Douglas Feagin, head of Ant’s international strategy. Tencent did not respond to Reuters’ emailed requests for comment. Who and what are behind Myanmar’s long-running civil war on China’s doorstep? Some compliance experts believe the deposits ought to be enough to raise red flags within financial institutions that follow global counterterrorist financing and anti-money laundering guidelines. Financial contacts with an organisation linked to drug trafficking or the arms trade pose a regulatory and reputational risk to firms even if they have not themselves done anything illegal, experts say. “If I handed this case to an internal committee there is absolutely no way they would do anything other than shut the account down immediately,” said an anti-money laundering officer at a global bank. Banks and financial firms in China, as elsewhere, are required by “know-your-customer” rules to check the identity of people or companies using their systems. Compliance experts said global financial firms typically use a number of automated tools to screen for individuals or groups that may even loosely be linked in media coverage or other publicly available information to potential criminal activity, and would view any such connections as a reputational risk. Some bankers working in China said it was very difficult to police cash flowing through their system, given the network was less mature than in the West and criminal and armed groups were increasingly sophisticated. They added that the sheer volume of transactions on mobile platforms made it impossible to monitor them all, so smaller payments were effectively invisible to banks and regulators. Insurgents openly raising tens of thousands of dollars from mainland supporters through Chinese platforms risks straining China’s relations with Suu Kyi, who has made ending decades of ethnic war her top priority, according to people who have studied Myanmar’s border conflicts. Beijing says it follows a policy of non-interference in domestic affairs of other countries. But some analysts such as Yangon-based Richard Horsey, a former United Nations diplomat in Myanmar, have long suggested China uses ethnically Chinese insurgent groups such as the Myanmar National Democratic Alliance Army, as a means of leverage over the government in Myanmar. After another bout of fighting between the alliance army and government forces two years ago, a Myanmar official accused China of meddling in the peace process, which Beijing denied. An alliance army spokesman did not respond to requests for comment. China turns blind eye to mainland supporters of ethnic Chinese rebels fighting in Myanmar “Allowing the MNDAA to fundraise in such an open manner within China will inevitably damage relations with Myanmar,” Horsey said. The alliance army says it is fighting for the rights of the Chinese-speaking ethnic Kokang people. China’s Ministry of Foreign Affairs did not respond to emailed request for comment. Beijing called for a ceasefire earlier this month after 30 people were killed in clashes between the rebels and troops in the Kokang region.
