Sikorski, who also serves as a deputy prime minister, announced the upcoming address in an interview with the YouTube channel Didaskalia.
He said the speech would offer a broad overview of Poland's foreign policy.
Asked about the content of his speech, Sikorski mentioned two main topics. First, he said "the definition of the Western alliance is changing," adding that a growing number of Poles "are allowing themselves to be seduced by anti-European ideology."
Such rhetoric, he said, creates "the illusion that there is a world where you can have all the benefits of EU membership and none of the obligations."
He warned that the international environment around Poland "is getting worse rather than better," making foreign policy more difficult and increasing the need for unity.
The second topic, Sikorski said, will be Ukraine, which he described as "Poland’s functional buffer against Russian imperialism."
In an earlier foreign policy address this year, Sikorski stressed the need to strengthen Europe's defence capabilities and maintain close ties with the United States.
He said Poland seeks to enhance national and international security through both the European Union and NATO in response to Russia's war in Ukraine.
He warned that the biggest threat would be a collapse of Western unity, adding that Poland "cannot afford to be alone."
Sikorski argued that Europe faces its most challenging geopolitical environment in decades and cautioned against a return to great-power rivalries that sideline smaller states.
"Europe faces an existential choice: unite and act as a heavyweight or risk becoming sidelined," he said at the time.
In a 2024 speech to parliament, Sikorski outlined Poland’s strategic foreign policy goals during what he called a historically crucial moment shaped by Russia’s invasion of Ukraine.
He emphasised Poland’s alliance with the United States and urged continued support for Kyiv.
