European Council President Herman Van Rompuy, right, and Poland's Prime Minister Donald Tusk, left, speak with German Chancellor Angela Merkel during arrivals for an informal dinner at the Copernicus Science Center in Warsaw on Thursday, Sept. 29, 2011. Poland is welcoming European Union leaders on Thursday for what is expected to be a key event of its EU presidency: a two-day summit aimed at keeping alive the prospect of the bloc's eastward enlargement. The summit in Warsaw is to focus heavily on Ukraine, which has been negotiating free trade and association agreements with the EU, a milestone for the former Soviet state in its hoped-for path toward deeper integration with its wealthier neighbors.
