this is a slogan!!
a slogan needs to be as simple as possible!
so i think that " One world, one dream" can already send out the message of 「同一個世界,同一個夢想」!!
Also, a slogan can be gramtically wrong!
For example,
"Impossible is nothing"--> It should be " Nothing is impossible"
one can have the meaning of all, and the same~~
i hope that u can understand

sorry, it should be grammatically.....not gramtically
You are right, but if we add suitable object & adjective to beautify or I rather say to make a more complete sentence, than it will appear more meaningful & positive.
