KYIV, Sept 26 – The United States will participate in the initiative of the Group of Seven (G7) to provide Ukraine with a gratuitous loan of $50 billion, but the amount of their contribution will depend on changes to the EU sanctions regime against Russia, Bloomberg said, citing sources familiar with the discussions.

"The US told the European Union that it will contribute $20 billion to a massive Group of Seven-led Ukraine aid package if the bloc tweaks its Russian sanctions regime as planned to make it more predictable," the agency said.
