Next time you should write a brief of cover letter to the email recipient as it is a good way to communicate professionally.
I have a glance at your essay, still found that there are things you may have to work on.
Firstly, you haven't sought for details on this programme, which you should write your reasons relevant to that ( I attached the file for you, so, have a look!).
Secondly, please note that you will have to pay for the return flight between Thailand and China, are you opk with this condition?
You can write based on the format I suggested above, and the most important thing is you need to clarify to yourself what "global leadership" is.
so that you can write based on a clear idea to yourself.
