Poland pledges to be Ukraine's 'most reliable' supporter.

The Polsat news agency quoted Prime Minister Tusk as declaring that Poland would join the security agreement after a meeting with Ukrainian President Zelensky in Kyiv on January 22. This commitment, officially known as the Joint Statement in Support of Ukraine, was signed by G7 leaders, including Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States, along with the President of the European Council and the President of the European Commission.

The signatories pledged to provide Kyiv with “modern military equipment,” military intelligence, training, and economic aid, with the goal of ensuring “a sovereign Ukraine within internationally recognized borders,” including territories annexed by Russia such as Donetsk, Luhansk, Kherson, Zaporzhye, and Crimea. Meanwhile, Ukraine agreed to crack down on corruption and human rights abuses in preparation for future “membership in the Euro-Atlantic Community.”

Poland's former nationalist government was one of Ukraine's strongest supporters, pledging more than 3 billion euros ($3.27 billion) in military aid to Kyiv and lobbying Western allies for more advanced weapons. However, relations between Warsaw and Kyiv deteriorated last September after Ukraine filed a complaint with the World Trade Organization (WTO) over Poland and several other EU countries' ban on the transfer of Ukrainian grain, arguing that the move harmed their own producers.

Mr. Tusk, a pro-EU politician who headed the European Council from 2014 to 2019, said earlier this month that he would “never allow anyone in the Polish government to build their position on anti-Ukrainian sentiment.”

Following his meeting with President Zelensky on January 22, Prime Minister Tusk announced his readiness to finalize negotiations on the joint production of weapons and ammunition on Ukrainian territory and emphasized that Poland would play a crucial role in the post-conflict reconstruction of Ukraine.
