Alestovich, an adviser to the Ukrainian president's office, said Russia and Ukraine are expected to sign a peace agreement within one to two weeks, up to May.
Alestovich also added that the territorial claims made by the Russian side are unacceptable and that the Ukrainian side is ready to continue negotiations on the remaining issues.
This is no longer known to be the first time Ukraine has changed its mouth.
Initially, Ukraine compromised on joining NATO, saying that it could not join NATO, but other countries had to guarantee Ukraine's security.
After that, Ukrainian President Zelenskiy publicly stated that NATO does not accept Ukraine, and he is no longer entangled in whether to join NATO.
More crucially, Zelenskiy also said that the territorial issue can also be discussed.
The president has said that territory can be discussed, and now the Ukrainian side has repented and refused to talk about the territorial issue.
And similar capriciousness, there have been several times, said good can be negotiated, on the negotiating table is not good, talked several times did not talk about the results.

After the meeting between the Russian and Ukrainian foreign ministers, there seems to be some progress, and both Russia and Ukraine have expressed their hope of reaching a written agreement.
However, in the fourth round of negotiations, halfway through the talks, the Ukrainian side said that there were so-called "technical problems", directly ignored the discussion, and postponed to the day after the talks.
What is a "technical problem"? That is to say, off-site factors, such as power outages, disconnections and the like.
But how can such technical problems arise in such negotiations, which are related to the fate of the country?
In fact, it is halfway through the talk, and I have to report to the United States and discuss what to do. If the United States has no opinion, then the next negotiation should be able to make some progress, if there is no opinion, then do not let up, continue to spend time with Russia.
Previously, the Russian side said that ukrainian representatives have been communicating with the United States during the negotiations, how can such negotiations produce results?
Judging from the current posture of Ukraine, it should be to delay time and consume Russia according to the requirements of the United States.
First release the signal of peace talks, sit at the negotiating table, let the Russian army be silent for a while, and then show its uncompromising position and continue to fight.
Ukraine just wants to tease Russia through this kind of repeated pulling, to see if it can force Russia to be anxious and make some irrational moves.
Even if russia cannot be pushed, the purpose of consuming Russia can be achieved.
So the question is, can Russia afford it?
Judging only from the current situation, the Russian economy will definitely be hit to a certain extent, but this does not mean that Russia cannot afford to spend.
Russia is a big food producer as well as an energy power.
Now Western sanctions against Russia have triggered a new round of global supply crisis, the most serious problems in the food and energy sectors.
As long as Russian production is not affected, trade will not stop, and even if trade is blocked, Russia can be self-sufficient.
It will not be impossible to live even a few days, which is doomed to Russia's consumption.
What the United States wants to achieve is to shake Putin's position, reduce the living standards of the Russian people through sanctions, and then take the rhythm to let the Russian people oppose Putin.
But it can't happen overnight, and putin's support in Russia soared after the conflict broke out.
So, in every way, Russia is consuming energy. What's more, now that the conflict has only been around for 20 days, Russia will not launch a special military operation if it cannot hold on to it for 20 days.
