MOSCOW (REUTERS) - Russia does not intend to demand early repayment of US$3 billion (S$3.9 billion) which it lent to Ukraine last year, President Vladimir Putin said in an interview with German TV channel ARD, a transcript of which was released by the Kremlin on Saturday.

"If we do it (demand repayment) the whole financial system will collapse. We have already decided that we will not do it. We do not want to aggravate the situation," Putin said.

"We want Ukraine to get on its feet at last."

ARD is broadcasting some comments on Saturday and the full interview on Sunday.

Under the terms of the loan, which Russian extended last December in the form of a purchase of Ukrainian Eurobonds, Russia can demand early repayment if Ukraine's debt exceeds 60 per cent of its gross domestic product.

Putin also said that Russia's state-owned Gazprombank had the formal right to demand early repayment of US$3.2 billion loans to Ukrainian energy company Naftogaz, but his remarks implied that it also would not do so.

Putin said that Western sanctions against Russian banks are harming Ukraine's economy, as Russian banks have extended US$25 billion in loans to Ukraine.

"If our European and American partners want to help Ukraine, how can they undermine the financial base limiting our financial institutions' access to world capital markets? Do they want to bankrupt our banks? In that case they will bankrupt Ukraine," Putin said.

Despite the sanctions, which he said were causing losses to Russia, Putin said he was confident that Russia's economy would grow next year by 1.2 per cent, with 2.3 per cent growth in 2016 and 3 per cent growth in 2017.

His comments were at odds with forecasts by the Russian central bank, which projects growth of 0-0.1 per cent over the next two years.

"Of course we expect the situation to change for the better. Of course we expect the Ukrainian crisis to end," Putin said.

"Of course we want to have normal relations with our partners, including in the United States and Europe."
