LVIV, Ukraine (Reuters) -Ukrainian President Volodymyr Zelenskiy called on Monday for new international sanctions against Russia over its invasion of Ukraine, proposing a boycott of Russian oil and other Russian exports and a halt of exports to Russia.

       Western sanctions imposed over Russia's military assault have already isolated Russia to a degree never before experienced by such a large economy.

       Zelenskiy said the economic pressure needed to be increased, calling in effect for an international trade embargo on Russia. [L2N2VA07O]

       "If the invasion continues and Russia has not abandoned its plans against Ukraine, then a new sanctions package is needed ... for the sake of peace," he said in a video address, mentioning a boycott of Russian oil and oil products in particular.

       "Boycott imports to Russia - if they do not adhere to civilised rules, then they should not receive goods and services from civilisation - let the war feed them," he said.
