The United States and the Czech republic signed the SOFA treaty (Status of Forces Agreement) on the conditions of the presence of the American soldiers at the planned US radar base in London, the Czech news agency CTK said yesterday.

The 34 articles of SOFA, sighed by US Secretary of Defense Robert Gates and his Czech counterpart Vlasta Parkanova, were formulated after 16 months of negotiations.

The document will only relate to the US personnel who will be connected with the radar base, Parkanova said previously.

The application of the treaty on other cases of the stay of US armed forces is only possible upon a consent of the Czech Republic that would be expressed in harmony with the constitution, she added.

Under the treaty, the US military and civilian personnel at the planned US base will be within the jurisdiction of Czech courts with two exceptions.

The exceptions refer to the criminal acts committed by Americans while on duty and their criminal acts against the security and property of the United States or any other US personnel at the base.

The Czech Republic has kept full sovereignty and ownership right to the area and any property whose use was allowed to the US armed forces, according to the Czech government.

The area of the radar station will be still the Czech Republic's territory and all the property that will be built there by US armed forces will become the Czech Republic's ownership upon completion, it added.

The two sides eventually reached a compromise on tax issues, which was the stumbling block for a long time during the whole process of the Czech-US negotiation.

The tax exemption will only apply in a limited fashion to the US firms and their employees who pay a similar tax in the United States. Other suppliers and their staff will be subjected to the Czech legislation, the treaty said.

The treaty determines that all US personnel will be equipped with special IDs issued by the Czech authorities.

After an informal meeting of NATO members' defense ministers on Friday, Gates and Parkanova also signed the Declaration on Strategic Cooperation between the two countries.

The Czech Defense Ministry has repeatedly dismissed speculations that the declaration and negotiations similar to those about Hercules are linked to Washington's plan to install its missile defense radar base on Czech soil. However, cooperation was lunched after the signing of the main treaty this summer.

The United States plans to build a radar base in the Czech Republic, along with an interceptor missile base in Poland, as part of its East European missile defense shield.

The main treaty on the radar base was signed by U.S. Secretary of State Condoleezza Rice and Czech Foreign Minister Karel Schwarzenberg in early July.

Russia is strongly opposed to the deployment of the system, saying it poses a threat to its national security. Czech opposition parties and some 70 percent of the country's citizens also oppose the project.

The radar treaties are yet to be ratified by the Czech parliament. It is not clear whether the government will muster enough votes for the treaty's ratification in parliament.
