“The United States and the United Kingdom enjoy a truly special relationship, … the United States has no closer ally and no stronger partner than Great Britain,” said Obama at a joint news conference with Cameron in the White House, adding that the two allies have been addressing common challenges ranging from terrorism to economic recovery, from non-proliferation to climate change.

Obama said that he and Cameron discussed the bilateral relations and common concerns, including sanctions on Iran, peace in the Middle East, and war in Afghanistan. Politely, Obama offered the prime minister an opportunity to comment on BP, at which Americans have poured massive anger over the Gulf of Mexico oil disaster and the alleged role in the release of the Lockerbie bomber.

Cameron, who is here not only for his first official visit as British prime minister, but for extinguishing the fierce fire against BP, said that he “absolutely” understood Americans’ anger at BP following the oil disaster, which is believed to be the largest offshore spill in U.S. history resulting in a catastrophe for the environment, and for the fishing and tourism industry.

“We are clear here that BP should be blamed for what has happened in the Gulf, and have real responsibilities to cap the well, to clean up the spill, to pay compensation,” said Cameron.

Obama told the Australian Prime Minister Kevin Rudd and Indonesian President Susilo Bambang Yudhoyono’s decision in separate telephone conversations, said the White House press secretary Robert Gibbs in a statement.

“The president will make arrangements to be about to visit these two countries” and plans to hold bilateral meetings with MM. Rudd and Yudhoyono on the sidelines of the G-20 in July in Canada, “said the spokesman.
