WASHINGTON - The International Monetary Fund (IMF) and the World Bank Group (WBG) have called on countries to keep trade open as the world battles the COVID-19 pandemic, warning that export controls on medical supplies and other essentials could backfire.

At a virtual press conference during the just-concluded spring meetings of the two multilateral institutions, IMF Chief Economist Gita Gopinath said that this is not a time to restrict the trade of medical supplies and essential equipment around the world.

"It is very important that this does not become a future where we reverse all the gains that we've got from globalization," said Gopinath, in response to a question from Xinhua.

Echoing her remarks, Kenneth Kang, deputy director of the Asia and Pacific Department at the IMF, told Xinhua in a recent written interview that countries should avoid trade restrictions on medical and health products to ensure that they go to where they are most needed.

"Countries with limited health care capacity and resources will need international aid to prepare for and weather the pandemic," Kang said. "The health emergency is a powerful reminder of the need for policy coordination and solidarity in an interconnected world," he said.

The IMF official said that countries should cooperate to reduce tariff and non-tariff barriers that impede cross-border trade and investment and to strengthen global supply chains as the recovery takes hold.

Zhang Tao, deputy managing director of the IMF, told Xinhua that he hoped these supply chains would work as best as they can to maximize global production and supply, which makes global collaboration "essential."

"Today more than ever, the global economy would benefit from a more open, stable, and transparent, rules-based international trade system," Zhang said.

World Bank President David Malpass, meanwhile, said at a virtual press conference Friday that big countries need to step forward and pledge not to use the crisis as a reason to close or block the markets.

"We should allow markets to function, markets to clear and the supplies to go to those most in need," said Malpass, adding that China is exporting medical supplies to the rest of the world, which is "very welcome."

The IMF and World Bank's advocacy for free trade came as protectionist sentiments are growing across the globe amid the pandemic. Some 46 export curbs on medical supplies have been introduced by 54 governments since the beginning of the year, according to a report published on March 23, by Global Trade Alert, a trade policy monitoring initiative.

Thirty-three of those export curbs have been announced since the beginning of March, "an indication of just how quickly new trade limits are spreading across the globe," the report showed.

Aaditya Mattoo, chief economist for East Asia and the Pacific Region at the World Bank, said it is a bit understandable for countries to impose export restrictions, but these actions are "almost always counterproductive."

"If each country imposes restrictions, then the global price increases even more than it would have. And it can end up being a self-defeating policy," Mattoo said at a recent press call, in response to a question from Xinhua.

The World Bank economist also noted that such measures would hit those countries who rely on these badly needed medical supplies, especially poor countries, which import a lot of drugs, ventilators and masks.

Despite that, Jeffrey Sachs, a renowned economics professor at Columbia University, told Xinhua that he thinks there will be more protectionism in Western countries, both in the United States and the Europe.

China will have to work hard to secure long-term supply chains and two-way trade, including with Association of Southeast Asian Nations (ASEAN), Africa and South America, said Sachs, also a senior United Nations advisor.

"I believe that China, Japan, (South) Korea, and ASEAN should work hard for a swift recovery and open trade amongst themselves," said Sachs. "East Asia could be back in business because East Asia never lost control of the epidemic."

As the global economy is on track to shrink "sharply" by 3 percent this year due to the pandemic, the IMF chief economist highlighted the importance of keeping trade open in global recovery.

"The world needs a healthy recovery. It needs a strong recovery. And that will not come about if the world de-globalizes because that would severely reduce productivity in the world," Gopinath said. "And that's the last thing we want at this time."
