yes...from what i have read on the internet a couple of years ago there is paintball in HK, but they use a different caliber of paint...much smaller to the standard .68 caliber that the rest of the world is using. i also read that they used this smaller caliber, because paintball is considered dangerous and illegal. they use a marker that looks similar to the spyder...but with really small hoppers (im talking hoppers the size of your fist!) hopefully they adopt the standard .68 caliber that the rest of the world uses.
anyhow...if i stumble upon that website again i will post the link up here...and if i come across any new info on paintball in those two countries; ill post it up here for you.
hope this helps
*EDIT* guess what, i was able to find the original site i visited a couple of years ago...and it looks like they have adopted the standard .68 caliber paintball size.
