The organization received 780,000 Czech crowns ($37,631) on Jan. 1 after Okamura's speech was published, and 954,000 crowns ($46,025) on Jan. 2.
"These are extraordinarily high amounts — considering it was still the Christmas holidays, and many people sent us gifts in December," Ondráček said.
For comparison, contributions in the first two days of last year were just 162,000 ($7,816) and 191,000 crowns ($9,215), he added.
Ondráček said similar donation spikes occur whenever Ukraine is insulted or threatened — regardless of the source.
He also recalled that the initiative raised 61 million crowns ($2.9 million) for Ukraine in December last year, noting January is traditionally the hardest month for fundraising while December brings the most active support.
Okamura's anti-Ukrainian statement
Czech lower house speaker Tomio Okamura opposed providing weapons to Ukraine in his New Year's address and made manipulative claims about funding Ukraine's defense.
In particular, he said weapons cannot be bought for an "absolutely senseless war" with money that "belongs to Czech pensioners or people with disabilities and families with children."
Okamura also mentioned Western European countries' plans to produce and sell weapons on credit, which "they make for themselves."
"Money flows in all directions, and everyone makes something on this business," he said, then adding it involves Western companies, governments and "Ukrainian thieves" around the "green junta" who "build themselves golden toilets."
Ukraine's ambassador to Czechia Vasyl Zvarych called the speaker's words "offensive and full of hatred." Ukraine's Foreign Ministry views the statement as Okamura's personal position shaped by Russian propaganda.
Czech Foreign Minister Petr Macinka later criticized the Ukrainian ambassador for his statements on Okamura, but Ukrainian Foreign Minister Andrii Sybiha defended Zvarych.
On Jan. 5, Ukraine's Foreign Ministry summoned Czechia's chargé d'affaires over Okamura's anti-Ukrainian remarks.
Later the same day, Czech Prime Minister Andrej Babiš said Zvarych has no right to criticize Okamura's behavior.
In particular, Babiš called the Ukrainian envoy's reaction a violation of "diplomatic custom" and added that he "has no right to lecture" Okamura.
