WASHINGTON. July 30 - Ukraine's foreign minister welcomed U.S. and European sanctions on Russia announced on Tuesday and pledged Kiev would not attack cities now controlled by pro-Russian separatists in its drive to re-establish control over its territory.

Pavlo Klimkin, in an interview with Reuters, supported the convening of a new international conference to end months of violence in eastern Ukraine and said he had discussed the idea with U.S. Secretary of State John Kerry earlier in the day.
