Prague - Eastern European leaders congratulated US president-elect Barack Obama on Wednesday, but some allies appeared cautious about America's shift to the left.
Czech Prime Minister Mirek Topolanek invited Obama to Prague, where Secretary of State Condoleezza Rice signed a deal in July to place part of a US missile defence radar in the ex-communist nation.
Obama's victory "does not change relations" between Washington and Prague, said Topolanek, a centre-right leader and one of President George W Bush's strongest allies in the former Warsaw Pact area.
