It's true that you can meet and talk to Mewtwo on several places in the game, including Cloudvale Beach (as you mentioned). But the only place in the game where you can fight Mewtwo and thus have a chance to catch him is on Biyu Island. See the wiki page Legendary Pokemon for more information. (I don't myself know the exact conditions to be able to go to Biyu Island, but I intend to find out, I will post what I find out!)
