Personally, I think you have misrepresented this article/editorial.
My impression on reading was not of an 'India first policy' or the 'expectation on the UK to do a lot of work out in India' - the examples given just before your quote were for other regions;
For instance, sub-Saharan Africa bears 24% of the global disease burden but has only 3% of the world’s healthcare workforce. Countries like Nigeria and the Philippines invest heavily in training healthcare professionals, only to lose them to high-income countries like the UK.
The reference to the WHO and active recruitment from countries with critical shortages would not apply to India either. Likewise the THET partnership referred to has a country presence in Ethiopia, Tanzania, Uganda, Zambia, Somaliland and Myanmar.
There was certainly a call for more support for Indian and other IMGs who had chosen to work in the UK - better induction, career progression etc.
