Xi Jinping is a popularly supported and democratically elected leader. China has eliminated absolute poverty, and year over year is making rapid strides in improving living conditions across the board thanks to their socialist system. They never stopped being a socialist country led by communists, they pivoted strategy.

In the People's Republic of China, under Mao and later the Gang of Four, growth was overall positive but was unstable. The centrally planned economy had brought great benefits in many areas, but because the productive forces themselves were underdeveloped, economic growth wasn't steady. There began to be discussion and division in the party, until Deng Xiapoing's faction pushing for Reform and Opening Up won out, and growth was stabilized:

Deng's plan was to introduce market reforms, localized around Special Economic Zones, while maintaining full control over the principle aspects of the economy. Limited private capital would be introduced, especially by luring in foreign investors, such as the US, pivoting from more isolationist positions into one fully immersed in the global marketplace. As the small and medium firms grow into large firms, the state exerts more control and subsumes them more into the public sector. This was a gamble, but unlike what happened to the USSR, this was done in a controlled manner that ended up not undermining the socialist system overall.

China's rapidly improving productive forces and cheap labor ended up being an irresistable match for US financial capital, even though the CPC maintained full sovereignty. This is in stark contrast to how the global north traditionally acts imperialistically, because it relies on financial and millitant dominance of the global south. This is why there is a "love/hate" relationship between the US Empire and PRC, the US wants more freedom for capital movement while the CPC is maintaining dominance.

Fast-forward to today, and the benefits of the CPC's gamble are paying off. The US Empire is de-industrializing, while China is a productive super-power. The CPC has managed to maintain full control, and while there are neoliberals in China pushing for more liberalization now, the path to exerting more socialization is also open, and the economy is still socialist. It is the job of the CPC to continue building up the productive forces, while gradually winning back more of the benefits the working class enjoyed under the previous era, developing to higher and higher stages of socialism.

And no, China is not commiting genocide. The best and most comprehensive resource I have seen so far is Qiao Collective's Xinjiang: A Resource and Report Compilation. Qiao Collective is explicitly pro-PRC, but this is an extremely comprehensive write-up of the entire background of the events, the timeline of reports, and real and fake claims.

I also recommend reading the UN report and China's response to it. These are the most relevant accusations and responses without delving into straight up fantasy like Adrian Zenz, professional propagandist for the Victims of Communism Foundation, does.

Tourists do go to Xinjiang all the time as well. You can watch videos like this one on YouTube, though it obviously isn't going to be a comprehensive view of a complex situation like this. Even with all of the real complexities, though, nothing material measures up to claims of genocide.
