Energy and business minister Greg Clark said the Hinkley nuclear plant deal will bring the UK into line with other major economies and provide a "fair and consistent approach" to national security implications.
"It is important that the right balance between foreign investment and securing the national interest is met, and that is exactly what these changes will achieve," he told Parliament on Thursday.
These changes mean that while the UK will remain one of the most open economies in the world, the public can be confident that foreign direct investment works always in the country's best interests.
Why does the government want a new nuclear plant at Hinkley Point and why has it proved so controversial?
Government officialscan't provide any detail about how a national security test for future critical infrastructure deals will be applied.
The government approved new nuclear power plants back in 2006 but the plan for Hinkley was only given the go ahead 10 years later.
