While the Liberal Democratic Party and Liberal Party will jointly tackle Japan's mounting problems, they will also try to seek support from other parties to stabilize the government, Prime Minister Keizo Obuchi said Thursday.

"The two parties will cooperate with each other with the new conservative principles in mind and try to utilize the strengths of each party for a synergistic effect on the nation's politics," the prime minister told a news conference after the launch of the new coalition Cabinet.

Obuchi also said the coalition government will try to negotiate with other parties because it lacks a majority in the Upper House.
