US interest in Indian Human Spaceflight Program

This release from PIB caught attention, for it mentions:

The United states has also expressed interest to collaborate with India on Human Space Flight as stated in the joint statement of Indian Prime Minister and US President during November 2010.

We had previously heard from the media about Boeing offering to help with the Indian Human Spaceflight Program. That could have possibly involved India co-developing (or buying in harsher terms) a variant of the CST-100 that Boeing has been developing for the CCDev Program. But, there hasn't much news on willingness of NASA, the official government space entity, to support India in it's Human Spaceflight ambitions. This old bit news points to NASA's "interest" in assisting India although whether such an assistance would be in India's interest is a different question altogether.
