CHICAGO (AP) — Ukraine Prime Minister Denys Shmyhal kicked off a United States visit Tuesday with multiple stops in Chicago aimed at drumming up investment and business in the war-torn country.

He spoke to Chicago-area business leaders before a joint news conference with Penny Pritzker, the U.S. special representative for Ukraine’s economic recovery, and her brother, Illinois Gov. J.B. Pritzker.

Shmyhal’s trip comes comes as Congress is considering an aid package for Ukraine, Israel and other allies.

“We would warmly welcome the participation of Illinois companies in projects related to the recovery of Ukraine,” he told reporters, calling it the country’s “most difficult time” in recent history.

He cited World Bank estimates of $486 billion needed for recovery over the next decade. For example, more than 250,000 residential buildings that have been damaged or destroyed since Russia invaded in 2022, he said.
