The GNP difference on Gaeseong and the US-ROK FTA (Yonhap):
The left wants it included:
A free trade panel of South Korean lawmakers visited an inter-Korean joint industrial complex in the North Wednesday to promote the inclusion of the inter-Korean made products manufactured in North Korea into the free trade deal between Seoul and Washington, National Assembly officials said...
"The Kaesong industrial complex is not simply an economic venture, but an important initiative for peace in the Korean peninsula," said the lawmakers in the statement, asking the negotiators from the U.S. and South Korea to include the Kaesong made products in the FTA.
The GNP doesn't think it is important enough to worry about:
Panel members of the main opposition Grand National Party decided not travel together to the Kaesong industrial complex, saying "Including the Kaesong made products is not a decisive matter regarding the FTA."
