Well you did not get what I meant. I meant that through the infrastructure development, it is actually taking the lands and ports for itself, for making military and naval bases. And it does not matter if it is nowhere in exporting arms. It is competing with every top nation in terms of increasing its defense capacity.
I have read about the Chinese investments in countries such as Sri Lanka, Myanmar, and Maldives, especially the ones involving ports and other infrastructural facilities. They seems to be purely for economic purposes. There is no chance that China will get permission to set up naval bases in return for this investment (not talking about Myanmar, there are Chinese bases already there).
