The United States will suspend tariffs on Ukrainian steel for one year, the Commerce Department said, citing the damage Russian President Vladimir Putin's war in Ukraine has done to the industry.

"Some of Ukraine's largest steel communities have been among those hardest hit by Putin's barbarism, and the steel mill in Mariupol has become a lasting symbol of Ukraine's determination to resist Russia's aggression," the department said in a statement, referring to the plant that became the last redoubt of government troops fighting Russians for their city.
