BUENOS AIRES, July 22 (Reuters) - Finance ministers and central bankers from the world's largest economies meeting in Argentina said heightened trade and geopolitical tensions pose an increased risk to global growth and have called for greater dialogue, according to a draft communique from the meeting.
The draft reviewed by Reuters, which is still subject to possible revisions, also noted that emerging market economies are better prepared to adjust to external shocks but they still face challenges from market volatility and reversals of capital flows.
