India has criticised the British government's decision not to recognise coronavirus vaccine certificates issued by Indian authorities, calling it a discriminatory policy that will impact its citizens who want to travel to that country, according to Reuters.

Foreign Secretary Harsh Vardhan Shringla said the new rules unveiled last week, which take effect next month, could force India to impose "reciprocal measures” if it wasn't resolved.

The new rules require Indians visiting the UK to quarantine themselves for 10 days and undergo Covid-19 tests even if they are fully vaccinated with the Indian-made AstraZeneca vaccine.
