All agreements reached between Ukrainian President Viktor Yanukovych and his Russian counterpart Vladimir Putin have to be implemented without delay, Ukrainian Prime Minister Mykola Azarov has said.

"All agreements that were reached by the presidents should be implemented without delay. Today we discussed a range of problems in this sphere and our delegations are constantly working on it," he told journalists in Moscow on Tuesday.

"We believe that all these agreements will be realized. Anyway, the Russian side has confirmed this to me at today's meeting with the head of the Russian government," Azarov said.

The premier also said that the first tranche of Ukrainian bonds would significantly strengthen Ukraine's forex reserves and help to settle a number of problems the country has faced at the end of the year.
