China's ride-hailing services provider Didi Chuxing is reportedly in talks with a group of global investors, including Japan's SoftBank Group, about forming a consortium to invest in US ride-hailing giant Uber, according to media reports.

US technology news site Techcrunch citied sources as saying that the group is close to finalizing the offer, which could be launched as early as this month. 

The consortium's offer includes direct investment in the company as well as purchases of shares from employees and other investors, the report said, adding the offer could range from 2 billion U.S. dollars to 10 billion U.S. dollars.
