The Intelligence Bureau (IB) has apparently proposed a ban on Chinese instant messaging platform WeChat, citing concerns over proliferation of such service could cause threat to national security, reports Economic Times. Citing an internal note, the report says that the deputy national security advisor Nehchal Sandhu has asked IB to discuss about the ban with the home ministry and the Department of Telecom. It notes that blocking the website is in accordance with the licensing conditions governing the ISPs could be one of the way to ban the service. Hence, it’s not clear whether the IB wants to ban only the WeChat site or the entire service. What’s surprising is the ET report doesn’t mention anything about whether the IB found any proliferation on the service for it be a threat to national security. It’s also surprising as to why the IB has suggested direct ban to the service instead of asking for more freedom to monitor the service in the country.
