Top legislators of the ruling camp will meet Thursday with a group of South Korean firms operating at the Gaeseong Industrial Complex in North Korea to discuss the North’s recent demands regarding operations at the business park.

Grand National Party Floor Leader Ahn Sang-soo, the party’s chief policy-maker Kim Sung-jo, and other top legislators will hear out the difficulties faced by South Korean firms at Gaeseong and discuss how the government plans to react.

The group of firms is urging for the ruling camp’s support, saying that if the South Korean companies are required to comply with the North’s demands, many of the firms will pull out of the park.

Last week, North Korea demanded South Korean firms operating in the park increase monthly wages for its workers by four times to 300 U.S. dollars.

The North also requested the South pay 500 million dollars in land-use fees for the Gaeseong business sites. The amount, which would cover rental fees for the next 50 years, is 31 times the amount stipulated in the original contract.
