This was stated by press secretary of Russian president, Dmitry Peskov, Censor.NET reports citing RIA Novosti.
Commenting on reports of possible deliveries of anti-tank missiles from U.S. to Ukraine and answering a question whether Moscow was going to initiate any talks with Washington regarding anti-tank missile delivery and whether it would support self-styled republics of the Donbas as a retaliation, Peskov said:
"Geopolitical thoughts should not be a reason for commenting. Our stance is well known: we believe that any country, especially those aiming at taking regulatory role, should avoid any activity that might provoke another level of tensions in a complicated region," Putin's spokesperson said.
Earlier, The Wall Street Journal cited some U.S. officials saying that Pentagon and the Department of State had developed a plan of delivery ant-tank missiles and other weapons to Ukraine.
