The Government disagrees with the US approach on many foreign policy issues, and this "will be made clear to the US President", the Tánaiste told the Dáil.
Ms Harney also said that security responses for the visit of President Bush to Ireland, which begins tomorrow, would be "proportionate to needs".
She said the Government would welcome Mr Bush on behalf of the EU and Ireland. "We have huge economic and political interest in good, friendly relations with the United States."
However, she added: "Clearly, we do not agree with the US approach on many foreign policy issues, and that will be made clear to the US President."
The Tánaiste was responding to Mr Joe Higgins (Socialist, Dublin West), who criticised the security operation in the Shannon area for Mr Bush's visit.
The Dublin West TD said for weeks the people in the Shannon area "have been subjected to an experience approaching that of a police state in order to make President Bush's visit possible".
He called on the Tánaiste to confirm that buildings in Shannon Industrial Estate had been "commandeered to set up a makeshift prison for protesters; our very own mini-gulag, complete with courtroom".
He asked were places being cleared in Limerick Prison, and he questioned how the Government could justify "taking thousands of gardaí from already overstretched duties to put a ring of steel around a man whom the Government will not dare parade in public, even at a hurling match in Croke Park as suggested by the US ambassador this morning."
He said Mr Bush "might declare the hurley a weapon of mass destruction, and bring in the US air force".
He questioned how the red carpet could be rolled out for a leader "who launched a criminal and illegal invasion in which thousands of children, women and men died or were maimed".
Ms Harney said that a temporary Garda station had been established, and the security response would be proportionate to needs.
She said that she would be meeting Mr Bush, and described the US as a "country that has been extraordinarily good to us politically in terms of the Northern Ireland peace process, and economically in terms of inward investment".
