From Amazon to Toyota and Aloca, major US companies are working to counter the impact of Tramp’s trade policy and blocking new tariffs.

These companies are trying to avoid confrontation with President Trump, but hope to exert the most influence to persuade Trump not to stop trade agreement or impose tariffs on various imported goods.

An informed but unnamed person said, the world’s largest online retailer and could computing company is discussing industry-wide advertising campaigns and broader government lobbying. 　

Amazon is not willing to comment.

Employees of Toyota Motor North America, a subsidiary of Toyota Motor Corp will attend a rally in front of the Capitol in Washington this week. The head has meet with important members of congress in recent weeks to discuss the potential impact of tariffs.

If Trump lets the US exit from the North American Free Trade Agreement (NAFTA) or impose a car tariff, General Motors (GM.N) will be affected. In the past year, GM executives also met with the government and Congress to raise concerns about trade issues. The company said in June that tariffs could lead to slowdown of business at home and abroad.

According to an informed source, General Motors, the largest automaker in the US will hire Essenstadt, the former director of US National Economic Council and international economic affairs adviser. The person said Essenstadt who has just left the White House this month will be responsible for GM’s public policy.

GM told Reuters that there was a vacant position but did not confirm the hiring. It’s unable to contact Essenstadt to comment.

Those companies that have been impacted by the Tramp’s steel-aluminum tariff which came into force in June, are also promoting privately relaxing policy.

The CEO of Alcoa told investors on conference call this week that company is discussing with Trump government, the US Commerce department and congressman, seeking to eliminate tariffs or seeking exemptions for Canadian aluminum products.

Alcoa said this week that it will generate an additional cost $14 million a month, mainly because the US puts a levy on aluminum products imported from Canada. Canada is the largest supplier of this company.
