I think that statement shows massive bias. There are massive differences between the two countries, but neither are beacons of freedom and human rights.
China has no elections at all, Russia has elections, but they're not remotely fair; any credible opposition tends to have "accidents". In both countries, criticism of the leader will be punished, though in different ways.
Neither has freedom of speech or a free press. It's much more structural in China, but in Russia you can still go to prison for years simply for calling the war a war. Any attempt at independent media gets harassed in various ways.
The main difference is in corruption and rule of law: Russia is pretty much entirely a mafia state now. Any assets you have are easily stolen by someone with better connections. Any of those rich oligarchs (who generally got wealthy through corruption and connections) who speaks out against Putin, is likely to lose what they have. In China, investments are safer, because China wants to attract business. And China does make real effort to fight corruption.
China's oppression of the Uyghurs is well documented, and is a process to destroy Uyghurs as a people: a form of genocide. I don't think Russia is doing anything remotely like that domestically, but both Putin and Russian state media do argue in various ways for genocide against Ukrainians.
China is a dictatorship through rule of law; they officially deny people their rights, but at least you know what to expect. Russia is a dictatorship through extreme corruption; you might nominally have rights, but you're likely to get an "accident" if you try to exercise those rights.
Russia is (obviously) far more aggressive and expansionist. China is more interested in soft power, expanding their economy, and influencing other countries through their economic expansion; much more in line with how the EU works, for example.
But no matter how you turn it, both really hate modern liberal values like democracy, free speech, free press, and don't care much for human and civil rights.
And sure, the US has a flawed democracy and has had its share of civil and human rights violations, some of which have still not been prosecuted (Guantanamo Bay), but at least nominally they do care about those issues, many of the people care about those issues, and demand improvement on those issues. Admittedly, there's also a very vocal minority that seems to prefer turning the US into an authoritarian dictatorship (more likely Russian-style and China-style), but they're a minority and they failed at their coup.
Like I said, the US is far from perfect, but if the EU needs an ally, the US is still the only real choice. The EU should probably learn to stand on its own feet and become more independent from the US, but it should not be naive about Russia and China (which it absolutely has been).
