The Italian government official who led the country's response to the L'Aquila earthquake has condemned relief efforts in Haiti as a disorganised "vanity parade", ahead of an international conference on rebuilding the devastated country, the Guardian wrote.

Guido Bertolaso, the head of Italy's civil protection service, said there had been a fundamental lack of leadership thus far in foreign aid missions to Haiti, warning also that the large US military mission in the country was not entirely helpful.

"The Americans are extraordinary, but when you are facing a situation in chaos they tend to confuse military intervention with emergency aid, which cannot be entrusted to the armed forces," he said. Italy's foreign minister, Franco Frattini, swiftly distanced the government from Bertolaso's comments. He had "attacked American and international organisations head on. The Italian government does not share these statements," Frattini told reporters in Washington.

Dozens of nations have sent rescue teams and relief supplies to Haiti. The effort involves government staff, troops and representatives from hundreds of separate charities and NGOs. The process has already been criticised as taking too long to bring desperately needed food, water and shelter.

Later on Monday, the Haitian prime minister, Jean-Max Bellerive, was expected to join Hillary Clinton, the US secretary of state, and ministers from Canada, France and other nations in Montreal to begin planning his country's long-term reconstruction.

Bertolaso led Italian relief and reconstruction efforts following the quake in April last year around the city of L'Aquila. The death toll was a relatively low 307 but thousands of buildings were damaged or destroyed.

Having arrived in Haiti on Friday, Bertolaso said he had seen "a terrible situation that could have been managed much better". "When there is an emergency it triggers a vanity parade. Lots of people go there anxious to show that their country is big and important, showing solidarity," he said.

He expressed doubt over the efficacy of having so many US military personnel involved. "It's a truly powerful show of force but it's completely out of touch with reality. They don't have close rapport with the territory, they certainly don't have a rapport with the international organisations and aid groups."
