Countries and industries were scrambling Friday to respond as President Donald Trump’s latest tariff hikes upend global trade and world markets.

China took the toughest approach so far, responding to the 34 percent tariff imposed by the US on imports from China by matching it with a 34 percent tariff on imports of all US products beginning April 10.

Trump was swift to criticize Beijing's move. “China played it wrong, they panicked -- the one thing they cannot afford to do," he wrote in a social media post, adding: “My policies will never change. This is a great time to get rich.”

Countries were taking different approaches as they sought a way to deal with the potential disruption to trade and supply chains. Taiwan’s president promised to provide support to industries most vulnerable to the 32 percent tariffs Trump ordered in his “Liberation Day” reciprocal tariffs announcement.

Vietnam, where the US is a major trade partner, said its deputy prime minister would visit the US for talks on trade.

Some, like the head of the EU's European Commission, have vowed to fight back while promising to improve the rules book for free trade. Others like Britain said they were hoping to negotiate with the Trump administration for relief.

Fighting Back
As with earlier countermoves to US trade penalties, Beijing hit back with targeted action, as well as its universal 34 percent tariff on all products from the US.

The Commerce Ministry in Beijing said it will impose more export controls on rare earths, which are materials used in high-tech products such as computer chips and electric vehicle batteries. Included in the list was samarium and its compounds, which are used in aerospace manufacturing and the defense sector. Another element called gadolinium is used in MRI scans.

China’s customs administration said it had suspended imports of chicken from two US suppliers, Mountaire Farms of Delaware and Coastal Processing. It said Chinese customs had repeatedly detected furazolidone, a drug banned in China, in shipments from those companies.

Additionally, the Chinese government said it has added 27 firms to lists of companies subject to trade sanctions or export controls.

For good measure, China also filed a lawsuit with the World Trade Organization, saying the US tariffs were “a typical unilateral bullying practice that endangers the stability of the global economic and trade order.”

Seize the Day
India was hit by a 26 percent tariff rate, lower than the 34 percent for Chinese exports and 46 percent for Vietnam. Its Commerce Ministry that it was “studying the opportunities that may arise due to this new development in US trade policy.” It said talks were underway on a trade agreement, including “deepening supply chain integration.”

The US was New Delhi’s biggest trading partner in 2024 with two-way trade estimated at $129 billion, according to US data. They have set an ambitious target of more than doubling their bilateral trade to $500 billion by 2030. Most pharmaceuticals and other medicines, important Indian exports to the US, are exempt from the reciprocal tariffs.

However, diamonds and other gems, another major export industry, are subject to the higher duties.

We Need to Talk
Most US trading partners have emphasized they hope negotiations can help resolve trade friction with Washington. Japanese Prime Minister Shigeru Ishiba said he was prepared to fly to Washington, in a last-ditch effort to forestall the 24 percent tariffs Trump ordered for exports from the biggest Asian US ally.

“The global trading system has serious deficiencies,” the president of the EU's European Commission, Ursula von der Leyen, said Thursday while on a visit to Uzbekistan. But she chided Trump, saying that “reaching for tariffs as your first and last tool will not fix it. This is why from the onset we have always been ready to negotiate with the United States.”

In Italy, Premier Giorgia Meloni told state TV she believes the 20 percent US tariffs on exports from Europe were wrong, but “it is not the catastrophe that some are making it out to be.’’ Her government planned to meet next week with representatives of affected sectors to formulate plans. “We need to open an honest discussion on the matter with the Americans, with the goal, at least from my point of view, of removing tariffs, not multiplying them,’’ Meloni said.

Vietnam's Foreign Ministry spokesperson, Pham Thu Hang, said Hanoi would keep talking with the U.S. to “find practical solutions” as 46 percent US tariffs threatened to decimate exports of footwear, electronics, textiles, and seafood.

“If enforced, [the new tariffs] would negatively impact bilateral economic and trade relations as well as the interests of businesses and people in both countries,” Hang said in comments cited by state-run media, which reported that the deputy prime minister and former finance minister Ho Duc Phoc was scheduled to visit the US for trade talks next week.

A Helping Hand
Taiwan President Lai Ching-te said he will offer the “greatest support” to industries most impacted by the new tariffs. Taiwan's trade surplus with the U.S. is relatively high partly because the island is a major source of computer chips and other advanced technology. Lai said in a statement on his Facebook page, “We feel that this is unreasonable and are also worried about the subsequent impact these measures may have on the global economy.”

Lai said he instructed Premier Cho Jung-tai to work closely with industries that are impacted and to communicate with the public about their plans to stabilize the economy.

Japan's leader Ishiba and other governments also said they were preparing countermeasures to help industries cope.

Likewise, von der Leyen said the EU was consulting with steel and automakers, pharmaceutical companies and other industries about how to give them more “breathing space.”

Looking Elsewhere
Trump's decision to sharply raise tariffs on countries spanning the globe is “self-defeating,” Wang Huiyao, president of the Chinese think tank Center for China and Globalization, said in an interview.

The latest tariffs impose heavy burdens on some countries in Latin America, the Middle East, Africa and Asia.

It's a trade war with the world, Wang said, while China's strategy is to trade more with Southeast Asia and Latin America, with Europe, the Middle East and other developing nations.

“The likely outcome is that China will become the largest trading nation and its economy will be trading more with other nations and the US may ... become more isolated,” Wang said.
