Indonesia was scrambling to defend President Susilo Bambang Yudhoyono on Friday after U.S. diplomatic cables allegedly accused him of bribery, intimidation and using his position for self-enrichment.
Foreign Minister Marty Natalegawa said at a news conference that the claims were baseless.
"We find it especially unacceptable that it has been suggested as facts," he said.
He was responding to U.S. diplomatic cables _ obtained by WikiLeaks and provided exclusively to Australia's Fairfax Media _ that were published Friday in The Sydney Morning Herald and The Age newspapers.
Yudhoyono became the country's first directly elected leader in 2004 largely on a campaign to root out entrenched corruption and nepotism following the 32-year dictatorship of Gen. Suharto. He was easily re-elected in 2009.
Though credited by many with bringing political stability and economic reforms to the predominantly Muslim nation of 237 million, many problems remain.
Graft is widespread, the infrastructure in shambles and millions of people live in abject poverty.
The U.S. cables allegedly accused Yuhoyono of trying to influence judges and prosecutors to protect his own corrupt political allies.
The published cables also said he used the country's intelligence service to spy on his rivals that his family was trying to use his political connections for their own financial gains.
The U.S. ambassador to Indonesia expressed regret that the cables _ apparently written by his predecessor _ had found their way to the public but could comment little on their contents.
Information exchanged between the embassy in Jakarta and Washington is "preliminary, often incomplete and unsubstantiated," Ambassador Scot Marciel told reporters.
"This is not an expression of policy, not of our final decision," he said. "These documents should not be seen as ... representing the U.S. policy."
