Denis Mikhailov, who oversaw contacts with international rating agencies and western investors in the ministry, is being tried for passing a document concerning Vietnam's debt to Russia to two businessmen, and receiving a 87,000-euro car as "remuneration."
Vladimir Zherebenkov said the prosecutor had requested seven-year sentences to two other defendants in the case. The defense will make its final statement on Tuesday.
Mikhailov has denied the charges. The two other suspects in the case, Alexei Kirzhnev, head of the International Investment Bank, and Teimuraz Karchave, president of National VIP-club, have also pleaded not guilty to charges of giving the bribe and receiving the document.
The investigation into Mikhailov, who was arrested in December 2004, was opened by the Prosecutor General's Office. But last April, his case was transferred to the Federal Security Service.
The Finance Ministry has reportedly supported Mikhailov from the start, hailing his contribution to progress in talks with the Paris Club of creditor nations. Finance Minister Alexei Kudrin testified in court on July 6 in support of Mikhailov.
"I described him as an efficient and responsible employee," the minister said, adding that he hoped his answers would help the court reach an objective decision.
