Trump's Sweeping Tariff Policy Hits Developing Nations Hard, Sparks Global Economic Concerns

In a sweeping overhaul of U.S. trade policy, President Donald Trump has announced a dramatic escalation in tariffs, targeting dozens of countries with punitive levies under what he described as a "declaration of economic independence." The measures are set to take effect in early April and have already drawn sharp criticism from economists and global leaders alike, particularly for their impact on some of the world’s most vulnerable economies.

Among the hardest hit are developing nations in Southeast Asia and Africa—many of which are already struggling with internal crises. Myanmar, still reeling from a catastrophic earthquake and years of civil unrest following the 2021 military coup, faces a 44% tariff. Cambodia tops the list in the Southeast Asian region with a 49% rate, followed by Laos at 48%, Vietnam at 46%, Thailand at 36%, and Indonesia at 32%.

In South Asia, Sri Lanka is subject to a 44% tariff, while Serbia in Europe will face a 37% rate. Several African nations have also been significantly affected, including Lesotho (50%), Madagascar (47%), and Botswana (37%).

A 10% universal tariff on all imported goods is scheduled to begin on April 5, with the targeted reciprocal tariffs on specific countries coming into force on April 9.

“These are nations that have taken advantage of the United States for decades,” Trump stated during a press conference on Wednesday. “Today marks our economic liberation.”

However, trade and geopolitical experts caution that the true impact of the policy may be far-reaching and counterproductive. Dr. Siwage Dharma Negara, a senior fellow at the ISEAS-Yusof Ishak Institute in Singapore, noted that the real target of these tariffs appears to be China—but that the collateral damage will be significant across Southeast Asia.

“Chinese manufacturers have increasingly shifted operations to countries like Vietnam, Cambodia, and Indonesia to avoid U.S. tariffs. By targeting those nations, the administration hopes to indirectly strike at China’s export base,” he said. “But this strategy threatens jobs and investment in host countries, many of which rely heavily on export-driven growth.”

Stephen Olson, a former U.S. trade negotiator and visiting senior fellow at the same institute, warned that the move could push affected nations closer to China, undermining Washington’s strategic influence in the region.

“It’s hard to build productive partnerships when you’ve just dropped a ton of bricks on your trading partners,” Olson said. “The U.S. has essentially hung a sign at its borders that reads ‘closed for business’.”

He added that countries now face two difficult options: retaliate and risk escalation, or attempt to strike bilateral deals with Washington. “Neither outcome promises economic stability,” he said.

The timing of the tariff hike is also under scrutiny, as it coincides with cuts to U.S. foreign aid programs, including USAID funding for disaster relief and democratic development in regions already under strain. Humanitarian concerns are particularly acute in countries like Myanmar, where ongoing conflict and natural disasters have compounded hardship, and in Lesotho, which is battling one of the highest HIV infection rates globally.

Critics argue that the tariffs will not only disrupt global supply chains but also raise consumer prices in the United States, exacerbate inflation, and stifle economic growth.

“This is how you sabotage the world’s economic engine while claiming to supercharge it,” said Nigel Green, CEO of financial advisory firm deVere Group. “These tariffs will drive up prices on everything from food to smartphones at a time when inflation remains stubbornly high.”

As the global economic community braces for impact, analysts are watching closely to see whether the policy triggers retaliatory action from affected nations—or if a new wave of protectionist trade realignments begins to take shape on the international stage.
