India's telecom ministry has left out Chinese equipment makers Huawei and ZTE from its 5G trials, becoming the latest country to lock the firms out.
The ministry granted permission to a dozen firms - including Ericsson, Nokia and Samsung's network unit - to conduct a sixth-month trial of 5G technology.
Although Huawei and ZTE were not named, they were not banned from supplying 5G equipment to carriers.
India is the world's second-biggest market by number of phone users.
Major carriers Reliance Industries' Jio Infocomm, Bharti Airtel and Vodafone Idea will conduct the trials along with state-run MTNL.
