Some arts , whether chinese or japanese are more grappling/throws/locks, with some striking. Other arts are more striking than grappling/throws/ locks.
The japanese jujitsu based arts are more throw/lock / grappling orientated than the karate arts which are more strike oriented. ( I have a little experience in both).
With the chinese arts there is no clear line as with the japanese karate vs. jujitsu .(karate to be technical really okinawan?) THe chinese arts tend to be more split along the lines of north vs. south, shaolin vs tao, internal vs external and there is a wide range of things included there in.
AS far as wing chun there is the ability to throw or sweep an opponent if you choose to do so, but wing chun is based more towards striking and trapping than throws. ( I practice wing chun).

I dont claim to be an expert , just my thoughts.
