In a formal letter addressed to Joo Hyung-hwan, the minister of trade, industry and energy, Lighthizer called for the special Joint Committee Meeting to take place in Washington, adding that that U.S. has been suffering from a persistent deficit in goods trade with Korea.
"The special joint committee will deal with important trade imbalance issues and provide opportunities for the U.S. to solve problems related to access to the Korean export market", said Lighthizer in a letter to Joo Hyung-hwan, minister of trade, industry and energy of Korea.
"The South Korea government will voice our opinion that it is necessary for working-level officials from the two countries first to study, analyze and assess the effect of the KORUS FTA and check the reasons of the bilateral trade imbalance as we have made such suggestions at the Seoul-Washington summit last month", Seoul's trade ministry said in a statement.
Together with this, Lighthizer demanded that a special joint committee meeting be held in Washington, DC next month. Such formal notice was sent in a letter by U.S. Trade Representative Lighthizer to Korea's Trade, Industry and Energy Minister Joo Hyung-hwan.
