The need to fulfill promises of increased aid for Africa, and a general agreement between the United States and Russia on an approach to Iran's nuclear program took center stage as leaders from the Group of Eight industrial nations met Monday in Japan, The Associated Press reported.

President Bush, attending his last summit as a sitting U.S. president, underscored the importance of providing aid for Africa, calling on wealthy nations to provide mosquito netting and other aid to prevent needless deaths, the AP reported.

Basic items - - even equipment as basic as mosquito netting - - can reduce mortality rates in sections of Africa. Mosquito netting prevents children and others from dieing of bites from disease-carrying mosquitoes.

In 2005 the G-8 pledged to increase global aid to $130 billion, and increase assistance to Africa to $50 billion. ONE, a nonpartisan group working to end extreme poverty, predicted that the U.S. and the United Kingdom will meet their commitments, while France, Italy, Germany and Canada are off the mark, Bloomberg News reported Monday.

Increased global food aid likely

Economist Glen Langan, whose specializations include agricultural economics, said increased aid for food and agricultural development will likely be announced by G-8 leaders at the summit, or soon thereafter, due to the rising cost of food's impact on poorer nations. "The aid will be targeted to meeting basic needs first, but with an eye toward directing some funds to self-sustaining agriculture," Langan said, adding that Africa "has the potential to achieve food production gains greater than South America."

Oil fell more than $5 to about $140 per barrel Monday morning after Iran's foreign minister expressed confidence in talks with western governments regarding the nation's nuclear program, Bloomberg News reported.

Iran's foreign minister Manouchehr Mottaki told CNN talks are "in a new environment" and "new approaches" are possible.

A rising dollar Monday morning also helped push oil lower. The dollar strengthened against the euro and the British pound on expectation G-8 industrial leaders will verbally support the dollar at an upcoming economic summit in Japan.

Oil fell $5.14 to $140.15 per barrel Monday morning before recovering slightly to $141.30. The other major energy commodities also plunged in early Monday trading. Heating oil plummeted 13 cents to $3.97 per gallon, unleaded gasoline fell about 10 cents to $3.47 per gallon, and natural gas plunged 42 cents to $13.16 per million BTUs.

Economist Glen Langan, who argues that fundamentals (primarily rising demand) are the major factors determining oil's price, said legitimate progress on the Iran uranium enrichment issue would ease traders' concerns about Iran's supply. "Iran is still OPEC's No. 2 producer and a major exporter of oil, so lasting good news with regard to Iran will ease traders minds about tensions in and near the Persian Gulf. That will take some pressure off prices," Langan said. About 20% of the world's oil flows through the Persian Gulf and the Strait of Hormuz.
