China’s central bank has signed a pact with Macau’s financial regulators to bolster cross-border anti-money laundering measures.

In a notice on its website, the People’s Bank of China (PBC) announced on Friday without elaboration that it has signed a memorandum of understanding with the Macau Monetary Authority on bilateral exchanges on anti-money laundering regulations, information exchange mechanisms and on-site inspections.

The PBC also said that the mainland and Macau would adopt recommendations from a global anti-money-laundering body, the Financial Action Task Force, to toughen regional supervision against money laundering.

The agreement is the latest move in Beijing’s wider anti-graft drive, as Macau casinos have been considered a money laundering blackspot. Macau’s junket operators and high roller VIP industry have also come under increased scrutiny from authorities due to Chinese President Xi Jinping’s campaign to crack down on corruption and illicit transactions.
