(Reuters) -Carrier Global on Tuesday announced plans to invest $1 billion over five years in the United States, in response to President Donald Trump’s policies encouraging domestic production.

Global firms are boosting their investments and presence in the U.S. after Trump’s policies have pushed companies across sectors, including Apple (NASDAQ:AAPL) and Ford, to produce within the country and generate jobs.

The additional headwind from Trump’s tariffs has also caused companies to rethink their supply chains.

Carrier said the move would generate 4,000 jobs, as it aims to hire 1,000 U.S. service technicians, and train over 100,000 climate solutions service and sales professionals over the next five years.
