WASHINGTON (AP) - The Obama administration has imposed financial restrictions on 34 people and entities for helping Russian and Ukrainian companies evade U.S. penalties and other infractions.

WASHINGTON (AP) The Obama administration has imposed financial restrictions on 34 people and entities for helping Russian and Ukrainian companies evade U.S. penalties and other infractions.

The Treasury Department says the action helps "maintain the efficacy of existing sanctions" established after Russia's annexation of Crimea last year and support for eastern Ukrainian separatists.

Fourteen are linked to "serious and sustained evasion" or are subsidiaries of already sanctioned firms. The department called six separatists and two former Ukrainian government officials "complicit" in corruption or destabilizing Ukraine. Twelve were targeted for operating from Crimea.

Americans can't do business with those listed; any U.S. assets they have are now frozen.

John Smith, the department's sanctions boss, says Russia must adhere to February's cease-fire for Ukraine. He says Tuesday's sanctions match those of America's international partners.
