WARSAW, July 8 (Xinhua) -- Ukrainian President Volodymyr Zelensky and Polish Prime Minister Donald Tusk signed a bilateral security agreement in Warsaw on Monday, just one day before the start of the North Atlantic Treaty Organisation (NATO) summit in Washington.
The agreement spells out Poland's continued defense support for Ukraine, especially air defense. Poland also pledged to support energy security for Ukraine, and participate in reconstruction.
The European Union (EU) and 19 countries have signed similar agreements with Ukraine, Tusk noted.
The document includes practical bilateral commitments, not just "empty promises," he added. ■
