The plan to transform Manhattan’s Park Lane Hotel into a super tall 1,210-foot luxury condominium tower is getting a boost from a new backer.

Chinese developer Greenland Holding Group is buying a 41 percent stake in the future project from a Kuwaiti fund in exchange for shares in Greenland, which is also developing Brooklyn’s Pacific Park.

The framework of the deal — which was outlined in a Hong Kong press release that largely escaped attention here — could restart the project, dubbed One Park Lane.

In January, lead developer Steve Witkoff told Bloomberg that “ velocity” in the super-luxury market had slowed. That prompted Witkoff and his partners to halt efforts to raise money through the government’s EB-5 visa program, which is popular with Chinese investors, while continuing to operate the hotel.

Now, along with the new partner, pre-development financing is also underway for the project, sources told The Post. Witkoff did not return calls and emails for comment.

The new Gary Handel-designed skyscraper would sit on the southern end of Central Park, along what has become known as “Billionaire’s Row” — what the Hong Kong press release mistakenly dubs “Billionaire’s Circle.”

The release also proclaims a condominium sell-out value of $3.6 billion to $4.3 billion. To achieve that valuation, pricing for the 450,000 square-foot project would have to hit around $8,000 to $9,000 per foot.

While this is much more than current luxury pricing that ranges up to $6,000 per foot and averaged a high of $2,800 per foot in the first quarter, according to the latest Elliman Report, it is within the realm of possibility four years from now, when the new tower could be open for residents.

In addition to the trading of the interest in the One Park Lane project, the Kuwait Strategic Investor and Greenland Hong Kong will jointly establish an $8 billion Silk Road Integrated Real Estate Fund to target a variety of other real-estate projects.

This, they say, is in line with the Chinese President Xi Jinping’s vision to have more interaction and ventures with Middle Eastern countries.
