International Business

I think by better scope you mean better income, so here is the comparison:
Corporate law
According to the United States Bureau of Labour Statistics, the projected job growth for corporate lawyers is 6% (2014-2024) and their median annual salary is $ 1,15,000.
In India, after completing a course in corporate law, you can be hired by a business firm or a large MNC at a good salary package.
The starting salary depends on your skills and from which college you have completed your course. In general, you may get anywhere Rs. 25000 to 45000 per month. After some experience, you can easily get Rs. 50,000 to 1,00,000.
International trade law
According to the payscale.com, in 2016, international trade specialists made a median annual salary of $62,641 and the job growth is same as corporate lawyers.
In India, lawyers in this field are very less in number and this will give you the advantage to earn and in the beginning, you may earn from INR 40,000 to 60,000 per month and after some experience, it may go up to 15-20 LPA.
Salary packages shall vary on different factors like company, education, candidates skills, work experience, etc.
So which one has a better scope that you should decide based on your interests.
