"The preliminary investigation is over. We are currently examining the materials of the criminal case. The volume is very big," said Anatoly Yablokov, the lawyer of Tsniimash-Export CEO Igor Reshetin.
Reshetin, detained last month on charges of embezzlement and the illegal transfer of state-controlled technology, will have to remain in custody until February 9, 2007, under a November 29 ruling by the Moscow City Court.
The firm run by Reshetin was set up in 1991 as the export arm of Tsniimash, a leading rocket and space technology developer incorporating Russia's Mission Control Center.
The defendant is charged with transferring precision engineering technology to a Chinese corporation in violation of state export controls, and of diverting 30 million rubles ($1.14 million) through schemes involving front companies.
Two of his deputies - Sergei Tverdokhlebov and Alexander Rozhkin - are also facing criminal charges in connection with the alleged theft.
Analysts say Russian technology may have formed the basis of China's manned space program, w with two successful orbital missions carried out to date.
Reshetin's defense team said earlier they would appeal the court ruling extending his pre-trial detention to February 9.
"Prosecutors have not submitted any new evidence that could serve as a foundation for extending the detention of my client," Yablokov said following Wednesday's court hearing.
