The Ministry of Public Security has not found indications of corruption in banknote printing activities at the central bank, according to a government report.
State inspectors have looked into allegations that Australia's currency maker, Securency, paid bribes to Vietnamese officials to win a banknote material supply contract, but there were no signs of accepting bribes, the government said in an anti-corruption report sent to legislators last week.
The report, however, said there were "some shortcomings" in the banknote printing business at the State Bank of Vietnam.
Prime Minister Nguyen Tan Dung has asked the Ministry of Public Security and the Supreme People's Procuracy, the country's prosecution agency, to continue following the case, the report said.
Australia launched the investigation into Securency in 2009, and the high-profile corruption case has attracted public attention in Vietnam.
According to a report on The Age in September, Australian Federal Police already charged eight former senior executives with conspiring to pay multimillion-dollar bribes to officials in Asia in return for banknote printing contracts.
The government's report also provided updates on several corruption cases, including the scandal at state-owned shipbuilder Vinashin. It said investigators, as of September 26, found deliberate violations causing a total loss of more than VND800 million and they are expanding the probe.
