Prime Minister Yoshiro Mori promised Wednesday to call on oil producers to make efforts to stabilize crude prices, saying the recent surge in the prices could have a negative impact on the global economy.

"There is a possibility that the surge in crude oil prices will adversely affect the world economy," Mori said in a House of Councilors plenary session.

"We will make use of opportunities of international gatherings such as those of the International Energy Agency and the Asia-Pacific Economic Cooperation forum to share the notion that stability in oil prices is important . . . and call on oil producers" to work to stabilize them, Mori said.
