**North Korea, South China Sea to Top ASEAN Regional Forum Agenda**
Diplomats from 27 countries are meeting in Brunei, with North Korea's nuclear program and territorial disputes in the South China Sea expected to top the agenda.
The ASEAN Regional Forum that opened Tuesday includes delegates from all six nations involved in the nuclear disarmament talks with North Korea that were disbanded in 2008.
North Korea has in recent weeks proposed restarting the talks, but has shown few signs it is ready to give up its nuclear weapons.
On Monday, U.S. Secretary of State John Kerry said the United States, China, Japan, and South Korea are "absolutely" unified in their insistence that Pyongyang must denuclearize.
He also urged ASEAN to make progress on a code of conduct covering disputes in the South China Sea, where Beijing has overlapping claims with several Southeast Asian countries.
China, which has been reluctant to deal with ASEAN on the disputes, on Sunday agreed to hold "official consultations" with the regional body on a proposed code of conduct.
**Obama Closes Trade-Focused Africa Trip**
U.S. President Barack Obama has wrapped up his trip to Africa and says he is convinced that with the right approach the continent's people "can unleash a new era of prosperity."
Mr. Obama left Tuesday after visiting and speaking at a once-idle power plant in Tanzania that was restarted through a joint U.S.-Tanzanian effort.
There, the president promoted his new $7 billion program to give more Africans access to electricity, with the goal of boosting the continent's economies.
He ended his week-long visit to Africa with a ceremony at Dar es Salaam airport, where he was seeing off President Jakaya Kikwete and hundreds of cheering and flag-waving Tanzanians.
Earlier Tuesday, former president George W. Bush joined Mr. Obama for a wreath-laying ceremony to honor the 11 people killed in the 1998 bombing of the U.S. embassy in Dar es Salaam.
