Washington, Jumada I 25, 1436, Mar 16, 2015, SPA -- The United States said Monday it is prepared to "increase the costs" to Russia if it fails to comply with the terms of cease-fire agreements in eastern Ukraine, suggesting potential further economic sanctions against Moscow. In a meeting with visiting Ukrainian Finance Minister Natalia Yaresko, U.S. Treasury Secretary Jacob Lew said Washington would take action if Russia continued to undermine the stability and sovereignty of Ukraine. Last week, the United States imposed sanctions on Ukrainian separatists and a Russian bank, the latest in a series of financial penalties on Moscow and pro-Russian separatists in eastern Ukraine. --SPA 23:44 LOCAL TIME 20:44 GMT www.spa.gov.sa/w
