Why should figurative marks and product labels be registered as copyright in Vietnam?

Surprise, shock, bewilderment, anxiety, pessimism and a scenario that all doors are closed is a common state/feeling that many foreign trademark owners fall into when they discover that their trademarks, even their product packagings have been filed for trademark or industrial design registration by a third party in Vietnam. Other holders are desperate that the risk of business strategy in Vietnam will be broken down/jeopardized when they detect that their trademarks and/or their product labels being copied in their entireties, or only some minor changes thereof are made by the third parties for the purpose of business exploitation.
