Thousands of people gathered in the center of Kyiv on Sunday to send a message to Ukraine's president, who meets his Russian counterpart on Monday, that Ukrainians will not accept a peace deal at the cost of the country's independence and sovereignty.
"We are here because we are not satisfied with the peace at any costs ... the peace at the costs of capitulation," Inna Sovsun, a lawmaker of opposition Golos (Voice) party, told the rally.
President Volodymyr Zelenskiy and Vladimir Putin are meeting in Paris alongside the French and German leaders in a renewed effort to end a conflict between Ukrainian troops and Russia-backed forces in eastern Ukraine that has killed more than 13,000 people since 2014. Zelenskiy, who won a landslide election victory in April promising to bring peace, said this week that his first face-to-face meeting with the Russian president would give Kyiv a chance to resolve the more than five-year-old war in the Donbas region.
But many Ukrainians are concerned over a possible compromise with Russia, which they see as an aggressor seeking to restore the Kremlin's influence over the former Soviet republic and ruin Ukraine's aspiration to closer European ties.
The Ukrainian government wants to agree with Moscow on a sustainable cease-fire in Donbas, the exchange of all prisoners, and a timeline for the withdrawal of all illegal armed forces from regions under the control of Russia-backed separatists.
The leaders' meeting was arranged after Ukraine and separatists withdrew their military forces from three settlements in Donbas - implementing agreements reached between Russian, Ukrainian and separatist negotiators in September.
Kyiv also promised to grant a special status to territory controlled by the rebels and to hold elections there.
These plans, seen as a sign of Kyiv's capitulation, sparked protests in the Ukrainian capital.
According to an opinion poll of Ukrainians conducted by a think-tank Democratic Initiative and Kyiv's International Institute of the Sociology on Nov 4-19, 53.2% of respondents are against a special status for Donbass and 62.7% do not accept an amnesty for those who fight against the Ukrainian army.
"We are here so that the voice from Kyiv can be heard in Paris. Friends, we cannot make any concessions to Putin until the last sliver of Ukrainian land is free," ex-president Petro Poroshenko told Sunday's rally.
Relations between two countries collapsed following pro-Russian president Viktor Yanukovych's escape to Russia and Moscow's annexation of the Crimean peninsula in 2014, which prompted Western sanctions on Russia.
Historian Volodymyr Vyatrovych said many centuries and recent years of Ukrainian history showed Kyiv should not believe in Moscow's good will.
"Zelenskiy's new team seems to be returning to this erroneous strategy, which consists in the fact that we can agree with Russia," he told the rally.
