China has told India not to block its Huawei from doing business in the country, warning there could be consequences for Indian firms operating in China, Reuters reported on Tuesday, citing sources with knowledge of the matter said. From a report: India is due to hold trials for installing a next-generation 5G cellular network in the next few months, but has not yet taken a call on whether it would invite the Chinese telecoms equipment maker to take part, telecoms minister Ravi Shankar Prasad has said. Huawei, the world’s biggest maker of such gear, is at the centre of a geopolitical tug-of-war between China and the United States. U.S. President Donald Trump’s administration put the company on a blacklist in May, citing national security concerns. It has asked its allies not to use Huawei equipment, which it says China could exploit for spying.
