The head of Poland's ruling rightwing party on Tuesday called EU President Donald Tusk, a fellow Pole vying for a second term, "Germany's candidate" whose re-election would sow crisis.
Belgian Prime Minister Charles Michel tweeted "congratulations", and Mr Tusk sent a tweet saying: "Thank you for keeping fingers crossed and for heart-felt support".
Poland attempted to block the adoption of European Union council conclusions at Thursday's (9 March) summit, after 27 European Union leaders re-elected Donald Tusk as president despite fierce oppostion from Warsaw.
Ahead of the European Union leaders' summit in Brussels, current Ms Szydlo said Warsaw did not want Mr Tusk because he had criticised Polish government policies.
Under EU rules it would need a majority of at least 72 percent of the 28 leaders, representing at least 65 percent of the EU population, a European Council official told AFP.
The president of the European Council will now serve for another 30 months.

Sunday could be even colder, with a predicted high of 45 degree, a low of 32 degrees and a 70 percent chance of rain. It will be mostly cloudy, with a low of 27, and an east wind of 9 to 11 miles per hour .
The first task for the leaders on Thursday, when they will meet at 28 with Britain included, will be deciding on a new term for Tusk until the end of 2019.
"One can only hope that the conflict will be resolved so we don't have a great divide in Europe", Gabriel said, when asked about Poland's stance on Tusk.
PiS leader Jaroslaw Kaczynski holds Mr Tusk politically responsible for the 2010 plane crash in Russian Federation which killed his twin Lech Kaczynski, and all other 95 people on board.
Kaczynski has long said member states should be given more power within the bloc at the expense of European Union institutions. He said the EPP would expel Mr Saryusz-Wolski if he did not give up his bid to thwart Mr Tusk.
A Downing Street source said: "We've always been clear he was doing a good job, and that we supported him".
Their relationship with Germany, Poland's biggest neighbor to the West and its main trade partner, appeared to improve over the a year ago, however, compared to its frostiness when Kaczynski's PiS party last ruled Poland in 2005-07.
