A long-planned banking joint venture between China Merchants Bank Co. Ltd. (CMB) and the fintech unit of e-commerce giant JD.com Inc. fell apart after more than five years of preparation. CMB, one of the country’s largest commercial banks, said Friday that its board decided to withdraw an application to open China Merchants Tuopu Bank and terminate preparations. The decision came more than a year after the bank won approval from the top banking regulator to set up a direct banking joint venture with the financial services platform Jingdong Digits Technology Holding Co. Ltd. (JD Digits).
