The legacy of World War II, and related Polish legislation, has previously strained ties between Poland and Israel.
Thousands of Poles risked their lives to protect Jewish neighbours during the war. But research published since 1989 showed that thousands also killed Jews or denounced those who hid them to the German occupiers.
In 2018 the government was forced to back down and remove parts of a Holocaust law that imposed jail terms on people who suggested the nation was complicit in Nazi crimes, which had angered the United States and Israel.
