(QHA) -

Moscow may change its budget rules to cope with an additional population of about 2 million people in Crimea.

First Deputy Prime Minister Igor Shuvalov told German daily Die Welt, adding that Crimea needs investment in infrastructure that cannot be covered by existing funds.

"When a country gets 2 million new people ... which need big investments, this cannot be done by just diverting funds from existing state programmes," he was quoted as saying, adding that the roads and ports required "serious investments".

Russian budget rules limit government borrowing to no more than 1 percent of output and link spending to the long-term oil price. But Shuvalov said: "I think it is right for this rule to be changed for two million new Russian citizens in Crimea."
