AlQa'dah 21, 1432, Oct 19, 2011, SPA - South Korean President Lee Myung Bak and Japanese Prime Minister Yoshihiko Noda held a summit meeting here today. During the meeting, the two leaders decided to move forwards on economic cooperation. Lee said he and Noda, who arrived in Seoul Tuesday for a two-day visit, agreed to cooperate to resume talks to sign a free trade deal that has been stalled since 2004. "Also, we agreed that we will increase support for closer business ties in key sectors like electronic components and materials," Lee was quoted as saying by the German Press Agency "DPA". The leaders also agreed to increase their currency swap line to US$70 billion to increase liquidity in response to global economic uncertainty. Both leaders reaffirmed their commitment to cooperate more closely in their joint efforts to end North Korea's nuclear programme. Lee said he would be glad to visit Tokyo in response to an invitation extended by Noda, but a date has yet to be set for the trip.
