Elsewhere, China said it closed down the nation’s biggest “underground bank,” which has processed more than 400 billion yuan (NZ$100 bln) in illegal foreign currency transactions, as the authorities tackle corruption and try to restrain capital outflows that have hit all-time highs this year. About 370 people have been arrested or face lawsuits or other punishment in the case, the official People’s Daily reported over the weekend, quoting police officials. The case brought the total for underground banking and money-laundering activities to 800 billion yuan since April, the newspaper said.
