This is not well written but they probably mean there are are two courses:
1. quantitative methods to analyse international trade
2. financial tools for SMEs
I think this because they say there are 2 courses and the other interpretation would be that they had two course about the same thing - quantitative methods to analyse international trade and financial tools for SMEs
It would have been clearer if the wrote "...two training courses one on quantitative methods to analyse international trade and the other on financial tools for SME..."
