KIEV, June 16 - Ukraine's Finance Minister said on Tuesday Ukraine was fulfilling all its debt obligations despite strained restructuring talks and was not treating its $3 billion debt to Russia differently from its other bonds, Reuters reported.

Ukraine is negotiating with foreign bondholders to restructure $23 billion worth of debt, but talks have soured over a disagreement on the necessity of a writedown on the principal of the bonds.

In May, Ukraine passed a law allowing it to halt payments if a deal with creditors remained elusive, but Finance Minister Natalia Yaresko said the country has not yet called the moratorium.
