The United States opened the way for more exemptions from its steel and aluminum tariffs on Friday, after pressure from allies and intense lobbying from lawmakers, further diluting the measures just a day after they were formally announced.
President Donald Trump, who has broad powers to impose the tariffs of 25 percent on steel imports and 10 percent on aluminum, had already granted exemptions to Canada and Mexico, and has said there would be the possibility of industry exemptions, although he has not spelled that out.
After Trump opened the door, Brazil, Japan, South Korea, Australia and Europe clamored for special treatment, although Chinese producers called on Beijing to retaliate in kind.
"The president can do exemptions and my expectation is there may be some other countries that he considers in the next two weeks," Mnuchin said in an interview with broadcaster CNBC on Friday.
When Trump's tariffs were initially announced, stockmarkets went into a tail spin on concerns they would ignite a global trade war. Reaction has however been measured and counter threats have been carefully calibrated so far.
Those threats have been overblown, according to Dani Rodrik, Professor of International Political Economy at Harvard University’s John F. Kennedy School of Government, who is one of the world's leading experts on trade.
"The reality is that Trump’s trade measures to date amount to small potatoes. In particular, they pale in comparison to the scale and scope of the protectionist policies of President Ronald Reagan’s administration in the 1980s," Rodrik wrote on Friday.
Tokyo and Brussels rejected any suggestion that their exports to the United States threatened its national security – Trump's justification for imposing the tariffs despite warnings at home and abroad that they could provoke a global trade war.
"We are an ally, not a threat," European Commission Vice President Jyrki Katainen said.
China's metals industry issued the country's most explicit threat yet in the row, urging the government to retaliate by targeting U.S. coal – a sector that is central to Trump's political base and his election pledge to restore American industries and blue-collar jobs.
Brazil, which after Canada is the biggest steel supplier to the U.S. market, said it wanted to join the exemption list and Argentina made a similar case.
Japan, the United States' top economic and military ally in Asia, was next in line. Chief Cabinet Secretary Yoshihide Suga told a news conference that Japan's steel and aluminum shipments posed no threat to U.S. national security.
The European Union, the world's biggest trade bloc, chimed in. "Europe is certainly not a threat to American internal security so we expect to be excluded," European trade Commissioner Cecilia Malmstrom said in Brussels.
Malmstrom told reporters the EU was ready to complain to the World Trade Organization, and retaliate within 90 days. She will meet U.S. Trade Representative Robert Lighthizer and Japanese Trade Minister Hiroshige Seko in Brussels on Saturday when she will ask whether the EU is to be included in the tariffs.
She won support from German Chancellor Angela Merkel. Shares in European steelmakers fell, although Germany's two biggest producers Thyssenkrupp and Salzgitter have insisted the impact on them will be limited.
The target of Trump's ire is China, whose capacity expansions have helped add to global surpluses of steel. China is also the potential target of far more wide-ranging U.S. action over what Washington says is its theft of intellectual property and coercion of U.S. firms to share commercial secrets.
Beijing vowed to "firmly defend its legitimate rights and interests". Tariffs would "seriously impact the normal order of international trade," the Commerce Ministry said.
Last year, China imported 3.2 million tonnes of U.S. coal, worth about $420 million and nearly five times the amount it took in 2016. Trump has championed coal exports as demand from power firms at home weakens.
The dispute has fueled concerns that soybeans, the United States' most valuable export to China, might be caught up in the row after Beijing launched an inquiry into imports of U.S. sorghum, a grain used in animal feed and liquor.
South Korea, the third-largest steel exporter to the United States and a strategic ally on the Korean peninsula, called for calm. "We should prevent a trade war situation from excessive protectionism, in which the entire world harms each other," Trade Minister Paik Un-gyu told a meeting with steelmakers.
While carrying a message to Washington to push forward a diplomatic breakthrough over North Korea, South Korea's national security office chief Chung Eui-yong asked U.S. officials to support Seoul's request for a waiver, a presidential spokesman said.
