One of China’s most-wanted fugitives is a 51-year-old billionaire real estate tycoon who is waging war against its ruling Communist Party — from his $67.5 million penthouse overlooking Central Park.

Dissident Guo Wengui, who is living in a massive Fifth Avenue home while seeking political asylum, says he wants to shine a light on fraud in the Chinese government — but claims it is coming after him with corruption claims of its own.

Now his future is in even greater peril, he says, because one of his pals back home was convicted last week and sentenced for allegedly taking bribes from him.

Former top Chinese intelligence official Ma Jian was sentenced to life imprisonment after he said he took $15.9 million in bribes from Guo to expedite the developer’s real estate projects.

Guo, who denies the allegations, told The Post in his first interview since Ma’s conviction that the case has only increased the Chinese government’s death threats against him to stop him from speaking out against the regime.

The Communist Party of China “wants to break me. But I don’t crumble under pressure. I get stronger from it,” said Guo, perched on an antique desk in his apartment at the Sherry-Netherland.

The defiant businessman said that although Beijing has frozen his money inside the country, he is still living large thanks to outside funds from other investments and supporters.

“I have 60 custom-made Brioni suits and handmade Louis Vuitton shoes. I don’t care about things. I’m a Buddhist,” said Guo, wearing a $3,000 tie and sitting below a Roy Lichtenstein canvas in his mahogany-paneled office.

“But the CCP wanted to take everything away from me — my wealth, my freedom and my dignity. All of this helps show that they can’t,” he said.

Guo is already the subject of an Interpol “red notice” provisional arrest warrant at China’s request — but fortunately for him, the United States and China do not have an extradition agreement.

His posh penthouse has become something of a prison since Ma’s sentencing. Still, he’s never felt more free.

“In China, I had 200 bodyguards, and lots of property, but I was never free. In America, I have freedom because I trust the country and the system,” he said.

“So I am far more free here.”
