LONDON, June 23 - Ukraine can save $15.3 billion in payments on external bonds without a principal writedown sought by the government in its restructuring talks with creditors, Kristin Lindow, senior vice president at Moody's Investors Service, said in an interview with Bloomberg agency last week in London.

A failure in the talks, which so far have been "antagonistic," and an outcome that leads to a moratorium on debt payments by Ukraine would have long-term implications for the country's access to international bond markets, she said.
