US citizen accused of 'insulting' Vietnamese national hero. Daniel Hauer lives in Vietnam, is married to a local woman and speaks fluent Vietnamese. He has a wide local following on Facebook and Youtube for his English language teaching videos and his observations about Vietnamese and Western culture. But a joke about General Vo Nguyen Giap triggered widespread condemnation on social media. 

Hundreds of people are calling for him to stop teaching and leave the country. He has since posted an apology video, was summoned by the authorities and is now facing a fine or a warning. It is thought to be the first time a foreign citizen has had to appear before officials for comments posted online.

 Communist Vietnam has a high rate of social media usage, but exercises strict control over the internet, filtering out content deemed undermining of the government of its values.
