KIEV, Aug. 4 - Ukraine said it expected "decisive" negotiations this week after it sent a fresh debt restructuring proposal to a group of its largest creditors, with the threat of a moratorium on debt payments looming, Reuters reported.

Talks to restructure $23 billion of Ukraine's external public debt have dragged on for more than four months over a disagreement over the necessity of a writedown on the principal of the bonds; but on Friday a source said Kiev saw this week as a deadline for a deal.
