The nation’s largest business group on Monday vowed to work with Donald Trump on a wide array of issues they argue would grow the economy and create jobs.

The U.S. Chamber of Commerce said in a letter sent to the president-elect that he must tackle everything from infrastructure to tax reform once in office.

{mosads}”The business community has been particularly encouraged by your comments concerning our country’s need to rebuild infrastructure, develop all forms of U.S. energy, reduce and reform taxes and remove unnecessary regulations and modernize the federal rulemaking system, the Chamber wrote is its final “Dear 45” letter that was part of a yearlong writing campaign. 

“In addition, we have been pleased to hear that you plan to bring significant change to America’s healthcare and public education systems,” they wrote.

The Chamber urged Trump to expand global trade — an area where the business group and the New York businessman disagree at this stage.

“We should avoid any course of action that constricts, rather than expands, trade,” the group wrote.

Trump has said he would renegotiate the North American Free Trade Agreement and would pull the United States out of the Trans-Pacific Partnership, though that stance on the Asia-Pacific deal may change with Congress abandoning plans to ratify the agreement for now. 

The Chamber reminded Trump that trade promotion authority, which would speed trade deals through Congress, will be in place for his administration.

The business group also made an argument for immigration reform saying it is a “challenge that has roiled the country for years.”

“We hope you and Congress will chart a balanced course that increases security and enforcement while also improving America’s legal immigration and visa systems,” they wrote.

“As you know from your business career, the ability of companies to attract talent at all skill levels is a strong factor in keeping and expanding operations and jobs in the United States,” they said. 

Trump has talked about deporting millions of people living in the country illegally.

“In the days ahead, we will agree on many issues and we may disagree on a few, but we share your commitment to this country and we stand ready to work with you and the new Congress to unleash a new era of growth and opportunity.”
