Hello Rakhi 

In order to learn international trade you must do MBA if you have willingness and zeal to have career in this field. Because in second year of you MBA you will suppose to choose this as subjects along with major finance subjects such as financial statement analysis, investment banking, security analysis, project appraisal, international finance, financial risk management, corporate finance, wealth management etc.

you will get exposure to this subjects deeply only in second year of your course as most esteem business school will make you learn subjects of various fields.

So yeah doing MBA will help you to a great extent.

Good luck for your career ahead.
