Ukraine said on Wednesday that it officially broke diplomatic relations with North Korea.
North Korea earlier recognized independence of Moscow-backed separatist regions in eastern Ukraine.
Ukraine's foreign ministry said the move by North Korea carries no legal weight.
Ukraine's foreign ministry announced on Wednesday that it severed diplomatic relations with North Korea after the country recognized the independence of two Moscow-backed separatist regions.
"Ukraine today breaks diplomatic relations with DPRK in response to its decision to recognize the so-called 'independence' of the temporarily Russian-occupied territories in the Donetsk and Luhansk regions of Ukraine," Oleg Nikolenko, a spokesperson for the foreign ministry, wrote in a tweet.
Russian state media TASS reported earlier on Wednesday that North Korea had recognized the independence of eastern Ukraine's Donetsk People's Republic, citing separatist leader Denis Pushilin. In a separate article, TASS reported that North Korea's ambassador to Russia presented a document with official recognition.
In a statement, Ukraine's foreign ministry called the move "an attempt by Pyongyang to undermine the sovereignty and territorial integrity of Ukraine," slamming it as "a gross violation of the Constitution of Ukraine, the UN Charter and the fundamental norms and principles of the international law."
The foreign ministry said North Korea's recognition won't change Ukraine's internationally recognized borders and carries no legal weight. For some, the move sparked an opportunity to joke about whether there was any diplomacy between the two countries to begin with.
"Ukraine severed diplomatic relations with North Korea. In my 26 years in diplomacy, I was never aware we had them," former Ukrainian diplomat Olexander Scherba tweeted.
Days before Russia launched its February 24 invasion of Ukraine, Russian President Vladimir Putin signed a decree recognizing Donetsk and Luhansk as independent states — sparking widespread outrage.
Ukraine has fought rebels in the two Kremlin-backed regions since 2014. US and Western officials had warned Putin would try to use the regions to stage a pretext for a full-scale invasion. Even before the full-scale invasion began, the Kremlin-backed rebels controlled roughly one-third of the region.
Last month, Syria — a Russian ally — also recognized Donetsk and Luhansk as independent, the Associated Press reported.
Following major setbacks in the early days of the war, including failing to take Kyiv, the Russian military is gradually making progress in Ukraine's eastern Donbas region (Donetsk and Luhansk comprise the Donbas). In early July, Russia seized control of Luhansk. Russian forces now appear to be regrouping and reconstituting for further offenses in the coming days, according to a recent UK intelligence report.
Meanwhile, Ukraine is beginning to use Western-supplied equipment, including HIMARS (High Mobility Artillery Rocket System) from the US, to strike targets in Russian-controlled territory.
In an overnight address, Ukrainian President Volodymyr Zelenskyy said: "The occupiers have already felt very well what modern artillery is, and they will not have a safe rear anywhere on our land."
