Polish Prime Minister Jaroslaw Kaczynski said on Saturday that his four-day official visit to the United States had met his expectations.
Upon his arrival back home in Warsaw, Kaczynski told Polish reporters he was delighted that all the goals of the visit had been achieved.
During his stay in the United States, Kaczynski held separate talks with President George W. Bush, Vice President Dick Cheney and Secretary of State Condoleezza Rice.
Kaczynski said Bush told him that U.S.-Polish ties were in good shape and the United States attached great importance to the relationship.
He said the United States had expressed support for Poland's strategy of diversifying its energy supply, and praised Poland's participation in international military operations.
Kaczynski said he also discussed Poland's involvement in Washington's planned missile defense program with the U.S. leaders.
If the United States established a base in Poland to intercept long-range missiles, Warsaw must receive security guarantees, Kaczynski added, but giving no further details.
