Hun Sen, an avid user of Facebook, said at a hospital inauguration here that officials needed to be able to use applications such as WhatsApp, Viber, LINE, Telegram, WeChat, and Zoom to do their jobs such as organizing online meetings effectively. Hun Sen recently said he had set up groups on WhatsApp and Telegram to use his phone to coordinate with various government ministries. The 69-year-old Hun Sen had led Cambodia since 1985 when what evolved into the internet was still in its infancy and generally available only to academic institutions.
