Korea's presidential office, government and the ruling Saenuri Party on Thursday agreed to work together to support key state policies, amid rising concerns over a slowdown in economic growth and security threats posed by terrorists.

"There are piles of difficult issues to be solved, but we do not have much time," Prime Minister Hwang Kyo-ahn said. "But there is still hope if the ruling party, government, and presidential office expand cooperation by putting top priority on the country's future and the public's happiness."

The prime minister added the trilateral meeting should focus on speeding up labor and economy reforms, while beefing up security measures to better guard the country from terrorists groups such as the Islamic State.

Chung Jin-suk, the floor leader of the ruling Saenuri Party, echoed the view, adding the presidential office and the government must do more to communicate with the public.

"As the presidential elections will take place next year, we do not have much time," Chung said.

"Amid the slump in the global economy, the public has been struggling with various burdens," said Presidential Chief of Staff Lee Won-jong. He pointed out that the country must also cope with such issues as restructuring in some key industries.

"The public wants the government and the ruling party to unite, while the ruling and opposition parties should join forces to stabilize the country's economy," Lee added, highlighting the importance of trilateral cooperation.

Korea's presidential office has been trying to forge deeper ties with Saenuri, especially as its lawmakers continue to clash between various factions even after the painful defeat in the April 13 polls.

President Park Geun-hye, meanwhile, will invite all Saenuri lawmakers to a luncheon on Friday, where the chief executive is expected to ask the party for cooperation to push forward critical reform bills. (Yonhap)
