2. the US responded with 3-1-1
announced 3-1-1 on September 26, 2006
-for a short spell, this applied to US bound flights (in addition to internal flights)
3. apart from dutifully respecting the "US bound flights" policy, China implemented its own version of 3-1-1 for domestic flights
March 15, 2008
4. the "US bound flights" policy is no longer a big deal for the US, but enforcement still happens in China (sometimes)
