But what if the meetings surrounding the summit get heated, what if the "sherpas", the special word for the senior finance people from each country who are spending much of the week frantically trying to iron out differences, are so taken aback by the latest US solution to its problems that they really get stuck on coming up with a fresh formula?
With G-20 countries at severe odds on the dominant issue of US-led demands, South Korea basks in the spotlight of center stage. Jang Ha-sung, dean of the business school at Korea University, sees "China, India and Korea together as the largest portion of the emerging market countries".
