Tata is complaining about China but was itself a massive beneficiary of  an earlier round of globalisation which put it in the position to take over British Steel; sauce for the goose...

Late last year Tata put its Research and Development wing, which had been British  Steel's R&D department into a new Not For Profit organisation, so British Steel won't now have any patent licensing income.

Someone needs to look at how Tata has handled British Steel's R&D as it is possible for such conglomerates to load all the costs on one business sending it into loss but have the licensing revenue go elsewhere.
