Came across the book with the wonderful title of "Doing Business in India For Dummies" by Ranjini Manian. This combines business and cultural advice which would be useful for those doing business with, as well as in, India. Some of the advice on language, laws and customs will be familiar to those in the UK and Australia, but it is still worthwhile.
One aspect that I had not realized is that India adopted for its Indian Arbitration and Conciliation Act 1996, the model of the UN Model Law on International Commercial Arbitration (UNCITRAL). The result of this is that, as the book suggests, you can write arbitration into your contracts and more than likely avoid a long and expensive court case in the event of a business dispute.
For my own report on India, see: "Living in an Indian Village in Goa for Three Weeks".
