President Donald Trump's fulfilling of campaign promises is responsible for the recent stock market gains, Commerce Secretary Wilbur Ross told CNBC on Monday.

"We're lowering taxes, we're cutting regulations, we're stimulating the workforce, helping to develop the workforce of the future, unleashing our energy resources and redoing our trade agreements," Ross said.

"That's the whole package that President Trump was elected on, and it's the whole package that's driven the stock market to $4 trillion of gains since the election."

Ross appeared on "Squawk Box" at the 2017 SelectUSA Investment Summit outside Washington, featuring senior government officials and global business leaders.

Since the election, the Dow Jones industrial average has surged more than 16 percent, the S&P 500 has gained more than 13 percent, and the Nasdaq composite has risen 18 percent as of Friday's close.
