Two Pharmaceutical Firms have said they will invest more than £1bn in the UK, creating about 1,850 jobs.
Germany's Qiagen will develop a genomics and diagnostics campus in Manchester, creating up to 800 jobs.
The government said these biotech deals illustrated confidence it its industrial strategy, the details of which it is publishing later.
Business Secretary Greg Clark said the investments represented "a huge vote of confidence" in the government's plans.
"People don't make the investments of this scale that are for the long term if they don't have the confidence that we are building in this country a very attractive base," he said.
He said the government's white paper on industrial strategy would set out how the UK's strengths in life sciences, financial services, advanced manufacturing and the creative industries would be maintained and enhanced.
The strategy comes just days after official forecasting body the Office for Budget Responsibility (OBR) announced an aggressive downgrade of its UK growth forecast.
