The new monarch called Russia's actions "an unprovoked full-scale attack" and praised the "remarkable courage and resilience" of Ukrainians. He also noted that during his meeting last month with President Zelensky he took the opportunity to "express his personal support for the people of Ukraine".
The King concluded his statement (which you can read in full at the bottom of this article) by saying: "I can only hope the outpouring of solidarity from across the globe may bring not only practical aid, but also strength from the knowledge that, together, we stand united."
Charles's comments are in stark contrast to his mother's much softer tone when she released a statement regarding the invasion in August 2022.
Marking Ukraine's independence day, the late Queen wrote to Zelensky expressing hope for "better times in the future", adding: "It gives me great pleasure to send Your Excellency and the people of Ukraine my warmest greetings on the celebration of your Independence Day.
"In this most challenging year, I hope that today will be a time for the Ukrainian people, both in Ukraine and around the world, to celebrate their culture, history and identity."
This light touch was something the former monarch was well-versed in: while noting the "challenging" time the country was experiencing and hope that the country's circumstances would improve she diplomatically sent a message of support, without being drawn into taking a political stand.
This isn't the first time Charles has dipped his toe into the political sphere since becoming King; during his first Christmas message as monarch he referenced the cost-of-living crisis, which was deemed by some as too political.
The accusation of refusing to remain politically neutral has been levied at Charles for many years while he was Prince of Wales. In 2018 he responded to this by saying that he understood the roles of the heir and the sovereign to be different and that he would be required to express fewer opinions when the time came for him to take the throne.
One issue that the new King faces is the longevity of his term as Prince of Wales - the public is well-versed in many of his opinions that he was freer to express as heir.
The late Queen took the throne when she was only 25, which meant that the public's perception of her political beliefs was much more of a blank canvas.
The nature of the role of constitutional monarch requires total political neutrality, and while many will react positively to this strong statement in support of Ukraine, Charles may not be so lucky next time he steps into what can be deemed the political arena.
Queen Elizabeth made gentle neutrality look easy, but her son is unused to publicly holding back the way she spent most of her adult life doing.
Charles has begun his reign more forcefully and it remains to be seen how much this could potentially damage the institution of monarchy itself.
The King's statement in full (24 February, 2023)
It has now been a year that the people of Ukraine have suffered unimaginably from an unprovoked full-scale attack on their nation. They have shown truly remarkable courage and resilience in the face of such human tragedy.
The world has watched in horror at all the unnecessary suffering inflicted upon Ukrainians, many of whom I have had the great pleasure of meeting here in the U.K. and, indeed, across the world, from Romania to Canada.
Earlier this month I met President Zelenskyy at Buckingham Palace to express my personal support for the people of Ukraine. It is heartening that the United Kingdom, along with its allies, is doing everything possible to help at this most difficult time.
Therefore, I can only hope the outpouring of solidarity from across the globe may bring not only practical aid, but also strength from the knowledge that, together, we stand united.
