LONDON/KYIV (Reuters) - Ukraine wants its allies to be bolder in imposing sanctions on Russia, including by targeting banks that provide financial services to serving soldiers, a senior adviser told Reuters.

Vladyslav Vlasiuk, who advises President Volodymyr Zelenskiy's chief of staff, also urged allies not to fear that a tougher sanctions clampdown could drive some countries closer to Russia, describing such a worry as overblown.
