The document is to be inked after talks between Poland’s Andrzej Duda, who is on a three-day visit to Ukraine, and his counterpart Volodymyr Zelensky.
Krzysztof Szczerski, chief of staff to Duda, said: "The presidents will adopt a very important political declaration which summarizes and reviews all the most important aspects in bilateral relations, both in terms of security, the economic situation, and also the situation of national minorities in both countries, and historical issues."
Szczerski added that the declaration would be an “extremely important document that comprehensively outlines the strategy and goals of our joint Polish-Ukrainian policy and Polish-Ukrainian relations in various areas for the coming years."
Szczerski told reporters that Monday would also see Polish state-run oil and gas giant PGNiG signing a deal that will give it the right to take part in the privatization of the energy sector in Ukraine.
“We want to invest in Ukraine,” Szczerski said. “Thanks to this agreement, the way will be open for PGNiG to negotiate the possibility of entering the process of the privatization of the energy sector in Ukraine.”
During his visit to Ukraine, Poland’s Duda is also set to hold talks with Prime Minister Denys Shmygal and Parliamentary Speaker Dmytro Razumkov.
Duda started his trip to Ukraine on Sunday with a ceremony in a Polish military cemetery at Bykivnya in the capital Kiev to commemorate the 80th anniversary of the Katyn Massacre of Polish officers and intellectuals by the Soviets during World War II.
