>> Rising tensions over new US tariffs are shaking up a G20 meeting of world economic powers in Argentina this week. And the finance ministers gathered here are putting pressure on the US delegation to agree to draft language reaffirming America's commitment to trade and cooperation. Reuters' correspondent Luc Cohen is in Buenos Aires.
>> An early draft of the communique seen by Reuters includes the phrase, global trade and investment are important engines of global growth. Now, whether that phrase trade is an important engine of growth stays in the communique, is going to be crucial to measuring the commitment of these countries to the future of free trade worldwide because that communique requires unanimous approval.
So that means that the United States would have to approve that language. A G20 official tells Reuters that at the moment that's what they're discussing. So we'll see on Tuesday whether that language supporting free trade remains in the statement.>> The US tariffs on steel and aluminum announced last week could be followed by even higher tariffs on Chinese goods.
But the measures aren't just provoking a backlash overseas. American's largest retailers including Walmart, Target, Best Buy, and Macy's on Monday urged the president not to raise new barriers to trade.
