From my location to AWS network I am getting high latency

The challenge here is that the internet is a collection of networks all managed by different parties. There's not a central place where you can work on issues like this that are likely caused by specific internet networks behaving in ways which are detrimental to your network traffic. As an example, one network provider might choose to route traffic in a way which is longer for you but cheaper for them.

If you'd like AWS to investigate (and that's a good place to start) then you will need to create a request with the support team.
