G7 tightens sanctions on Russia in response to invasion of Ukraine

The U.S. and G7 allies imposed new sanctions against Russia to curb its war against Ukraine.
The sanctions targeted hundreds of individuals and entities helping Russia evade existing sanctions and continue its invasion.
The U.S. halted exports of consumer goods to Russia and added more companies to its trade blacklist.
The U.K. banned imports of Russian goods like diamonds, copper and nickel and sanctioned those involved in stealing Ukrainian grain.
The effectiveness of sanctions is debated, but officials argue they limit Russia's ability to wage war, even as Russia maneuvers to evade them.
