American allies including Canada have protested the planned protectionist move by the president, saying they shouldn't be covered by Trump's planned 25 percent tariffs on steel and 10 percent on aluminum.
He says the European Union has threatened tariffs on $3 billion-plus worth of US goods.
"Other countries' responses to tariffs will be a key determinant of their ultimate impact on aircraft demand, and China stands out here as a critical buyer of airplanes and a leading target of the administration's proposed tariffs".

Additionally, bin Salman will visit the Cathedral of St.Mark in Abbasiya where he will meet with Pope Tawadros II. Also, Al-Azhar Grand Imam Ahmed el-Tayib will receive the Saudi crown prince at Al Azhar Mosque on Monday.
White House trade official Peter Navarro, making the rounds of weekly talk shows, said excluding one country will create a slippery slope - he said tariffs would go up on the remaining countries, and everyone else would demand the same treatment as Canada.
However, US steel consumers would have less choice and could be forced to pay more for steel products. That is no showstopper, they contended.

Due to the high level of integration of the Canada-US steel industries, he added, "these proposals are going to hurt them every bit as much as they will hurt us".
Industries that consume aluminum and steel products add far more to U.S. economic output than companies which produce these metals.

Economists warn the measures themselves raise costs of inputs for goods produced in the U.S., and increase prices of imports to consumers.
China also condemned the move, with a Chinese foreign ministry spokesperson saying: "If all countries followed the example of the United States, [it] will undoubtedly result in a serious impact on the worldwide trade order".
Global trade has long taken place between countries that abide by the rules-based system led by the World Trade Organisation (WTO) and its rules and dispute-settling mechanisms.
The director of the World Trade Organization, Roberto Azevedo, responded coolly, saying, "A trade war is in no one's interests".
Earlier this year, Washington also slapped safeguard measures that push up the maximum import tariffs on residential washers and solar panels to 50 percent.
