Ukraine President Volodymyr Zelenskyy revealed some of his country's ground rules for a peace agreement with Russia on Sunday, but Russian authorities moved to censor the interview, perhaps because Zelenskyy also said that while Russian President Vladimir Putin claimed the invasion aims to "denazify" Ukraine, peace talks with Russia have not involved any discussion on Ukraine's supposed "Nazism."

Zelenskyy spoke with Russian media outlets, saying that his country is open to guaranteeing Ukraine's neutrality and its nuclear-free status, but its representatives will not sign any agreement until Russian troops withdraw from the country. The Ukrainian president also said that the entire process hinges on him personally meeting with Putin and the Ukrainian people agreeing to a referendum to change the Constitution – a referendum that cannot take place while Russian troops remain in Ukraine.

"We must have agreements with President Putin. The guarantors will not sign anything if the troops are not withdrawn," Zelenskyy said, according to the presidential office. A personal meeting would be "enough to start the process of troops withdrawal."

"The troops must be withdrawn, the guarantors will sign everything, and all this will start working. Ratifications in parliaments, a referendum in several months, and only then - amendments to the Constitution," the president explained.

A referendum is necessary "because only the people can decide that there can be such a status and such guarantors," Zelenskyy argued. "The referendum will take place in a few months, and the amendments to the Constitution will take at least a year. According to our current legislation."

The president noted that, during peace talks with Russian diplomats, "We do not discuss ‘denazification’ and demilitarization at all. I said that we will not sit at the negotiating table at all if we talk about some kind of demilitarization, some kind of ‘denazification’. For me, these are completely incomprehensible things."

ZELENSKYY CONDEMNS RUSSIAN MISSILE ATTACK ON HOLOCAUST MEMORIAL: ‘BEYOND HUMANITY … DAMN THEM’

Putin has attempted to justify his attack on Ukraine as an effort to "denazify" the country, playing on the Russian public's lingering hatred for the Nazi regime. Yet Zelenskyy is Jewish and had family members perish in the Holocaust. Russian officials have compared him to Jews who were forced to collaborate with Nazis.

Ukrainian officials have compared Russia's bombing of Kharkiv, Ukraine's second-largest city, to the Nazi assault on the city in 1941.

Zelenskyy previously condemned a Russian attack that damaged the Holocaust memorial of Babi Yar earlier this month.

"What will be next if even Babi Yar (is hit), what other 'military' objects, 'NATO bases' are threatening Russia?" Zelenskyy asked. "Sophie's Cathedral, Lavra, Andrew's Church? Whatever they dream about. Damn them."

Yet Zelenskyy said his diplomats and Russian representatives did discuss key issues such as guarantees of security, neutrality, and Ukraine's nuclear-free status, because "Russia calls NATO enlargement of the reasons for invading Ukraine."

The president also mentioned discussions about preserving the Russian language in Ukraine, and Zelenskyy said this issue "can be resolved through mutual respect fo the languages of all neighboring countries."

"We all speak the way we want and the language we want," he said. "We have more than 100 nationalities in the country. That's why I said: only a mirror respect for the history, languages, cultural values of all neighbors. I accept that. I am sure that our people will accept it if they want. Because all this will be decided one way or another by the people, the voters."

Russia quickly banned publication of the interview. Roskomnadzor, which regulates communications for Moscow, issued the ban, saying there could be action taken against the Russian media outlets that took part, which included "those that are foreign media outlets acting as foreign agents."

Zelenskyy responded by saying Moscow was afraid of a relatively short conversation with journalists. "It would be funny if it weren’t so tragic," he said, according to the Ukrainian news agency RBK Ukraina.
