KIEV (Reuters) - Debt restructuring talks between Ukraine's Finance Minister and a group of its largest creditors did not take place as planned on July 22 as technical aspects needed to be discussed, a source with knowledge of the negotiations said on Thursday.

Negotiations to restructure $23 billion (£14.8 billion) of debt have dragged on for over four months due to disagreement over the necessity of a writedown on the principal of the bonds.
