Andrii Sybiha thanked his Polish counterpart Radosław Sikorski on X on Sunday evening.
"We greatly value Poland'’s support during this difficult time and we know that Poles, just like Ukrainians, do not scare easily," Sybiha wrote.
Poland's foreign ministry said earlier on Sunday that "Russia's further threats and calls to diplomats to leave Kyiv show that the Kremlin is trying to bully Europe and undermine our support for Ukraine."
It added that "such measures, contrary to the principles of the international law, will not have the desired effect."
Russia "will neither wear Ukraine down nor shake European solidarity with the Ukrainian people," it also said.
Poland said it did not foresee any changes to the work of its embassy in Kyiv.
The EU's ambassador to Ukraine, Katarina Mathernova, took a similar line on X.
"Russia has a message for foreign diplomats in Kyiv: leave, or risk your lives. Our answer: We are staying," she wrote.
On Saturday, Russia's foreign ministry warned foreigners and diplomatic missions against staying in Ukraine or travelling there. Moscow said it would continue systematic strikes on "military targets" in Kyiv and other cities.
Moscow issued a similar appeal in May, which 50 countries described as a threat in a joint statement under UN auspices, the AFP news agency reported. Western missions stayed in the Ukrainian capital.
On Friday, Ukraine's foreign ministry denied a report by Britain's The Guardian newspaper that Western embassies were preparing to relocate to Lviv or Poland. It said it had received no such notifications from foreign diplomats.
Kyiv has come under heavy attack in recent weeks, mainly from jet-powered drones. Russia has hit infrastructure and, for the past few days, the bridges over the Dnipro river that link the two halves of the city.
