No changes to the United States' earlier decisions on the installation of a missile shield in Poland were discussed during US President Barack Obama's Moscow visit, Polish Foreign Minister Radoslaw Sikorski said on Wednesday.

"Whatever was said in Moscow will bear no influence on the shield decisions. What we do know is that such decisions will be made by the United States, Poland and the Czech Republic and not ( by) third countries, which is very good news," Sikorski told reporters here after meeting with visiting US Acting Assistant Secretary of State Stephen Mull.

Sikorski also said that talks on the location of Patriot missiles in Poland were scheduled for next week in Washington, according to the Polish news agency PAP.

Under a Polish-US accord signed last year, 10 ground base interceptors are to be installed in Redzikowo, northern Poland, as part of a larger missile defense system that would also include a radar system in the Czech Republic.

Russia objects to the anti-missile shield plan, warning that it will deploy a short-range missile system in its Baltic enclave of Kaliningrad bordering Poland, in response to the US plan.

US President Barack Obama has said he supports missile defense in principle but wants to make sure the system is reliable and does not detract from other security priorities.

Following Obama's talks with Russian President Medvedev on Monday, the US leader reportedly kept the door open for further discussions on Russia's concerns.

Poland first asked for the Patriot unit after Russia condemned the missile shield plan as a threat to its security.
