A gold-digging bride-to-be scooped up $287,000 in cash and gifts from her fiance then took the bounty and ran, leaving him at the altar, the jilted groom charges in a new lawsuit.

Spurned would-be spouse Jin Dong is suing his ex, Yu Qing Weng and her parents in Manhattan Supreme Court, seeking the return of his betrothal bounty.

Dong and Weng, who immigrated to New York from China’s Fujian province, were engaged in 2016. They’d planned a ceremony at a Queens banquet hall for January 2017.

“In exchange for the promise to legally marry him and in the custom of his native country, Jin Dong” paid the six figures for the wedding costs and gifts, he says in his Manhattan Supreme Court lawsuit.

The six-figure wedding fund was pooled from Dong’s friends and family, the suit says.

The Manhattan resident spent $55,833 on the venue, $3,300 for wedding photos, $1,800 for a master of ceremonies, $4,000 for a wedding procession, and $1,000 for the cake.

Additionally he paid his future parents-in-law a $63,000 cash dowry. Another $5,300 “gift of appreciation” went to his mother-in-law. The bride’s brother and grandmother each received $2,000 — “all in anticipation of the contemplated legal marriage,” the suit says.

Weng herself got $110,000 in cash and “exquisite betrothal gold jewelry valued at approximately $40,000,” according to court papers.

The couple enjoyed the sumptuous banquet, but then Weng dragged her feet when it came time to legally wed Dong in a civil ceremony, the suit says.

In August, she “left the home she shared with Jin Dong, never to return,” according to the legal filing.

“Weng took all of the money and jewelry she received in anticipation of the contemplated marriage with her when she left,” the suit says.

Her mom returned just $1,500 to Dong. He asked his ex and her relatives to return the rest of the money, but they’ve refused and he suspects the engagement was a sham.

“Yu Qing Weng never intended to legally marry the plaintiff,” Dong says in court papers.

Instead she induced him to propose to her “without any intention of keeping her promise to him in order to obtain the money and jewelry,” the suit says.

He’s suing to recoup the total $287,000 he spent on the party and gifts.

Weng and her parents did not return a message seeking comment.
