The G20 leaders’ summit was concluded in Delhi on Sunday under the chairmanship of India. The US termed the summit a ‘complete success’. “We are confident that it was a success. The G20 is a big organization. Russia is a member of the G20. China is a member of the G20,” Matthew Miller, an official spokesman for the US State Department, said at a regular press conference on Monday. He responded to a media question asking if the G20 summit was a success.
