It looks to me like a marriage between a balafon, which is a West African instrument
and a marimba, which is what happens to a balafon when you send it to the Caribbean, and given it some decades to evolve:
Marimbas are often metal, but usually when metal, the sound comes from metal tubes, like this one.
I would be interested to know what kind of sound it makes!
Wait -- are those chinese characters on the striking keys?
