LVIV, Ukraine, March 27 (Reuters) - Ukraine is willing to become neutral and compromise over the status of the eastern Donbass region as part of a peace deal, President Volodymyr Zelenskiy said on Sunday, even as another top Ukrainian official accused Russia of aiming to carve the country in two.

Zelenskiy took his message directly to Russian journalists in a video call that the Kremlin pre-emptively warned Russian media not to report, saying any agreement must be guaranteed by third parties and put to a referendum.

"Security guarantees and neutrality, non-nuclear status of our state. We are ready to go for it," he said, speaking in Russian.

But even as Turkey is set to host talks this week, Ukraine's head of military intelligence, Kyrylo Budanov, said Russian President Vladimir Putin was aiming to seize the eastern part of Ukraine.

"In fact, it is an attempt to create North and South Korea in Ukraine," he said, referring to the division of Korea after World War Two. Zelenskiy has urged the West to give Ukraine tanks, planes and missiles to help fend off Russian forces.

Zelenskiy later said in his nightly video address that he would insist on the "territorial integrity" of Ukraine in any talks.

In a call with Putin on Sunday, Turkish President Tayyip Erdogan agreed to hold talks this week in Istanbul and called for a ceasefire and better humanitarian conditions, his office said. Ukrainian and Russian negotiators confirmed that in-person talks would take place.

Top American officials sought on Sunday to clarify that the United States does not have a policy of regime change in Russia, after President Joe Biden said at the end of a speech in Poland on Saturday that Putin "cannot remain in power".

U.S. Secretary of State Antony Blinken said Biden had simply meant Putin could not be "empowered to wage war" against Ukraine or anywhere else.

After more than four weeks of conflict, Russia has failed to seize any major Ukrainian city and signalled on Friday it was scaling back its ambitions to focus on securing the Donbass region, where Russian-backed separatists have been fighting the Ukrainian army for the past eight years.

A local leader in the self-proclaimed Luhansk People's Republic said on Sunday the region could soon hold a referendum on joining Russia, just as happened in Crimea after Russia seized the Ukrainian peninsula in 2014.
