Group of 20 finance leaders on Sunday said that trade and geopolitical tensions have "intensified," raising risks to improving global growth, but they stopped short of calling for a resolution of a deepening U.S.-China trade conflict.

U.S. President Donald Trump said the "incredible relationship" he and China President Xi Jinping had would be "the very primary reason" they could make progress on trade, though he offered no specific solutions.

Trump and Xi are due to sit down for dinner at the end of the G20 summit in Buenos Aires.
