Polish and US negotiators planned to resume talks Wednesday on a proposed US anti-missile shield to be placed in Eastern Europe amid claims from the Polish prime minister that Washington is now "more likely" to consider Polish demands, dpa reported.
US chief negotiator John Rood was slated to arrive in Warsaw for talks that will continue through Thursday.
Polish Foreign Minister Radek Sikorski will head his side's team, replacing fired top negotiator Witold Waszczykowski.
Some dubbed the latest round the "last-chance talks" after Tusk rejected the latest US offer on July 4. Since then, Waszczykowski was fired on Monday after he accused the government of stalling on the deal for political gain.
Prime Minister Donald Tusk's government has been bargaining for military aid in exchange for letting the US base 10 interceptor missiles in Poland.
Tusk said his priority are Patriot rockets to be permanently stationed on Polish soil, and strengthened Polish air defence.
The Bush administration has already signed a deal with the Czech government on hosting a radar base as part of the system to be based in the two ex-communist countries.
Russia has strongly opposed the US project, despite assurances from Washington that it would be targeted against ballistic missile threats from nations like Iran, not Russia.
But Polish President Lech Kaczynski said last week that Russia's military assault on Georgia was an argument for joining the US plan.
