WARSAW, October 21 (RIA Novosti) - Poland is ready to take part in a reconfigured U.S. missile defense system, the Polish prime minister said on Wednesday.

Donald Tusk said after talks with visiting U.S. Vice President Joe Biden that the new missile defense configuration "is very interesting, and we would like to participate in it," adding that "we are ready for joint responsibility."

Biden is also expected to brief Poland's president on Washington's revised missile defense plans.

Biden's visit comes just over a month after U.S. President Barack Obama announced that Washington was scrapping the Bush administration's plans for a missile shield in Central Europe due to a re-assessment of the threat from Iran.

The missile shield would have seen the deployment of a radar in the Czech Republic and interceptor missiles in Poland. Russia had fiercely opposed the plans as a national security threat.

U.S. Secretary of State Hillary Clinton earlier said Poland and the Czech Republic would remain the key candidates to host a missile defense shield.

According to the Obama administration's new plan, land-based missile defense shields will not be implemented before 2015. Sea-based defense shields will be operating in the Mediterranean Sea up to 2015.
