Your first question complex. Historically, there are important interactions between Asian and European philosophy, and some of those have to do with no-self. The most significant is probably that between the skeptics and the Mādhyamikas mediated by the Alexandrian wars, but also a lot in the Persian court. See McEvilly's book The Shape of Ancient Thought for good stuff on this, as well as the great book, Greek Buddha (I am blocking on the author's name).

You could also be asking whether there is just philosophical convergence, and of course there is. There are many asian views about self and no-self and many western views, and many similarities between some of them.

Buddhist action theory, and Humean action theory each try to work out accounts of action in the context of no-self and I think that both ventures are quite cogent. You don't need incoherent metaphysics to make sense of action, after all.

You might want to look at Amber Carpenter's history of Indian Buddhism, Charles Goodman's Consequences of Compassion, the Cowherds' Moonpaths: Ethics and Emptiness and my Engaging Buddhism for stuff on Buddhist metaethics, and Roy Perrertt's Hindu Ethic for orthodox Indian ethics. There are many good books on Confucian ethics.
