US PresidentDonald Trumpon Sunday accusedUkraineagain of lacking "gratitude" for Washington's support againstRussia's invasion, as top US and Ukrainian representatives met in Geneva for talks on a proposal to halt the war.

"UKRAINE 'LEADERSHIP' HAS EXPRESSED ZERO GRATITUDE FOR OUR EFFORTS," Trump wrote on his Truth Social platform, while also re-airing frustration at the war's "HUMAN CATASTROPHE" and attacking his predecessorJoe Biden, but offering no direct condemnation of Moscow.

Trump's blast at Ukraine and the US allies reflected the Republican's annoyance over the war, which began when Russia launched its full-scale invasion of Ukraine in 2022, seizing and destroying swaths of territory.

Trump claimed in his presidential campaign last year that he would broker a peace within 24 hours.

However, his sporadic diplomatic efforts have made little ground and he faces fierce criticism from within his own party for anew 28-point plan being discussed in Genevathat would deliver several of Russia's key war aims.

While Trump has previously said he is disappointed in Russian PresidentVladimir Putin, he rarely criticises theKremlinleader directly or condemns the invasion, instead pressuring Ukrainian PresidentVolodymyr Zelensky.

In Sunday's social media post, he criticised European countries that he said continued to buy oil from Russia and called Biden "crooked Joe" for giving Ukraineweapons"free, free, free".

The only mention of Putin in the lengthy post was to claim that the Russian president thought "Now is my chance!" to invade Ukraine only because "Sleepy Joe" Biden was in office.

Zelensky has repeatedlyexpressed thanksfor the hugeUS militarysupport to Ukraine, which continues to battle the occupying Russian forces across a front hundreds of miles long.
