LONDON (AP) — Britain has agreed to increase cooperation with India in areas including trade, science and health as Indian authorities battle a surge in coronavirus infections that threatens to overwhelm the nation’s health care system. Plans for a “quantum leap” in relations between the two countries were released after a video meeting between British Prime Minister Boris Johnson and his Indian counterpart, Narendra Modi. Prior to the meeting, Britain announced 1 billion pounds ($1.4 billion) of trade deals with India, including an investment by the Serum Institute of India that will aid in the development of vaccines against COVID-19 and other diseases.
