Russia's deputy finance minister said earlier on Tuesday that he expected Venezuela to have problems repaying its debts to Moscow in comments made after Washington imposed sanctions on Venezuela's state oil firm.

The finance ministry issued a separate statement later on Tuesday, saying it still expected a payment of over $100 million (76 million pounds) to be made on time.

"No changes in the agreement have been introduced and correspondingly Venezuela must fulfil the obligations it has taken upon itself to the creditor," the ministry said.
