can the ending of a passage to india be regarded as a typical instance of modernist open endedness?

There is a sense of leaving us "up in the air", things aren't wrapped up neatly. What we do know is that Aziz, and the relationships he has with Brits and Indians, will never be the same. The last chapter is titled "Friends again". We expect things between Aziz and Fielding to go back to what they once were. This however can never be and we see the cultural wedge between them that will never disappear. In this sense the ending isn't open-ended.
