Both countries also signed an agreement, endorsed by 17 other countries, on fighting information manipulation by foreign actors.
The United States and Poland launched an international operation on June 10 in the Polish capital aimed at helping Ukraine counter Russian disinformation.
The group, which began work Tuesday, includes representatives from 12 countries, including NATO members such as Canada, France, Germany, Finland, Sweden, Italy, Lithuania, Latvia, Poland, Slovenia, and the United States, as well as Ukraine, the ministry said.
NATO and the diplomatic service of the European Union also participate in the group, the statement said.
He said China repeats every argument of Russian diplomacy related to the war in Ukraine in the information space, reported PolskieRadio24.pl.
“The challenge in information warfare is not only to know what the Russians are doing, it’s to also figure out what are the best ways to combat it,” Mr. Rubin told reporters at the U.S. Embassy in Warsaw on Monday.
He said the idea for the initiative came from the United States but that it was eagerly embraced by Poland, whose government is concerned by the damage that disinformation can pose to democracies.
Increasingly, Polish officials say Poland, which borders Ukraine, is also a target of sabotage and other disruptive measures by the Russian secret services.
Mr. Rubin, who heads the U.S. State Department’s Global Engagement Center, said Warsaw was a logical location for the center given the many officials who pass through the Polish capital to enter and leave Ukraine during the war.
Agreement on Disinformation
On June 10, Mr. Rubin and Mr. Chłoń also signed a memorandum of understanding on cooperation between the United States and Poland in countering information manipulation by foreign countries, according to a statement by the U.S. State Department.
According to the State Department, countering foreign manipulation of information requires its signatories to adopt a more active approach than “monitor-and-report” tactic. Countries that endorse it should adopt measures to safeguard freedom of expression, protect “marginalized groups,” ensure transparency in media ownership, and protect elections from foreign influence, the department said.
The countries should also dedicate a government institution to coordinate the fight against disinformation on a national level and participate in international efforts, the department advised.
Civil society, independent media, and academia should be involved in government-led initiatives to combat manipulation of information, the department said.
