Can my Chinese wife own my property if we do not register our marriage in China?

IF I MARRY A CHINESE LADY FROM CHINA IN AMERICA, BUT DO NOT REGISTER THE MARRIAGE IN CHINA, CAN SHE CLAIM A VEHICLE THAT I BOUGHT AFTER THE MARRIAGE AS HER OWN, OR AT LEAST 50%. NOT REGISTERING THE MARRIAGE IN CHINA, BUT BUYING THE VEHICLE IN MY OWN NAME, CAN'T I GIVE THE VEHICLE TO MY MOTHER, OR BEST FRIEND, AND SHE HAVE NO LEGAL CLAIM TO THE VEHICLE?
