Gazprom eyes $25B prepayment in China gas deal

• Gazprom (OTCPK:OGZPY) expects a $25B prepayment from China as part of its $400B contract, though the details and timing of payments and delivery of the gas aren't yet finalized, according to the Russian company's deputy chief executive.
• Gazprom's Alexander Medvedev says he will not reveal the price China National Petroleum (NYSE:PTR) agreed to pay for the Russian gas but insists it would be "complete nonsense" to suggest the deal would not make money.
• The lack of details of the contract has raised questions in Russia about whether the criteria for striking the deal were primarily political rather than economic.
