LONDON, Sept 18 (Reuters) - Ukraine's sovereign dollar

bonds rallied on Thursday, some to multi-month highs, a day

after the launch of a joint $150 million critical minerals

investment fund with the United States.

While all bonds, and Ukraine's gross domestic product-linked

warrant, made gains, the short-term 2029 issue popped the

highest, adding nearly 3 cents to bid at 68.75 cents on the

dollar, its highest since March.

U.S. support for Ukraine is crucial to the country's

grinding war with Russia, and many view the critical minerals

deal as a sign of Washington's long-term investment in the

country.
