G20 Attempts to End Disputes on Currencies, Trade Imbalances Steve Herman | Seoul 12 November 2010 South Korean President Lee Myung-bak opened Friday's Group of 20 summit by stating there has been "big progress" in the negotiations, but he gave no details. Summit spokeswoman Sohn Jie-ae says the president also asked leaders to compromise. "They started the session off with the South Korean president emphasizing the fact that the sherpas and the deputies were negotiating until the wee hours in the morning," she said. "He asked the leaders to take account of their efforts and that we should work together to get an agreement at the end of the day." The United States is finding little support for its proposal to set targets for trade balances. China is resisting any commitments on currencies that would make its exports more expensive. There are concerns that if the G20 does not reach a compromise, some countries may implement protectionist measures that could harm trade and growth. .
