When the Cold War ended, governments and companies believed that stronger global economic ties would lead to greater stability. The world is being pushed in the opposite direction by the Ukraine war and the Pandemic.

Unwinding is an important part of the economy. Hundreds of Western companies have stopped operations in Russia on their own because of the sanctions, which are being used by American and European officials to sever major parts of the Russian economy. Companies are reorganizing how they get their goods because of high costs and unpredictable delays in global supply chains.

Western officials and executives are rethinking how they do business with China because of the Chinese Communist Party's human rights abuses and use of advanced technology.

The United States and its allies forged post-Cold War economic and foreign policies that were adopted by rivals like Russia and China.

Edward Alden, a senior fellow at the Council on Foreign Relations, said that the world is headed toward a more divided world economically and politically.

I think the answer is yes, until it doesn't.

As the progressive left became more powerful, the opposition to globalization gained steam. The uncertainty of the economic order has been brought into relief by the outbreak of the Pandemic and the invasion of Ukraine.

President Biden warned the President of China that there would be consequences if Beijing gave material aid to Russia. China has criticized sanctions on Russia, and Le Yucheng, the vice foreign minister, said in a speech on Saturday that globalization should not be weaponized.

The result of all the disruptions may be a fracturing of the world into economic blocs, as countries and companies gravitate to ideological corners with distinct markets and pools of labor, as they did in the 20th century.

Mr. Biden frames his foreign policy in terms of unifying democracies against autocracies. Mr. Biden says he is creating a foreign policy for middle-class Americans that is centered on getting companies to move critical supply chains and manufacturing out of China and to friendlier countries.

The goal is given urgency by the fact that the world's most powerful companies have realized that they need to focus on not just efficiency and cost, but also resilience. Supply chains have been threatened once again by China's restrictions on Covid-19.

The economic impact of such a change is not known. The emergence of new economic blocs could lead to a massive reorganization of financial flows and supply chains that could lead to shortages and raise prices for consumers in the short term. Longer-term effects on global growth, worker wages and supplies of goods are harder to predict.

The deglobalization forces that could have profound and unpredictable effects have been set in motion by the war.

Executives have pushed for globalization to expand their markets and exploit cheap labor. Russia makes money from its exports of minerals and energy. The Group of 7 industrialized nations make up more than 50 percent of the global economy, while China and Russia make up 20 percent.

Despite worsening relations, trade and business ties between the United States and China are still strong. With the new Western sanctions on Russia, many nations that are not partners of America are more aware of the dangers of being economically tied to the United States and its allies.

All recent U.S. presidents have used the tactic of bringing in other nations to shield themselves from Western sanctions if Mr. Xi and Mr. Putin organize their own economic coalition.

A professor of international political economy at Harvard Kennedy School said that interdependence can be weaponized against you.

The war in Ukraine probably put a nail in the coffin of hyperglobalization, he said.

China and Russia have taken steps to wall off their societies, including putting strict censorship mechanisms on their internet networks, which have cut off their citizens from foreign perspectives and some commerce. China is trying to make critical industries self-sufficient.

The Wall Street Journal reported that Russia and China were talking about using the renminbi to pay for oil purchases. The governments want to move away from dollar-based transactions, which are a foundation of American global economic power.

For decades, prominent U.S. officials and strategists claimed that a globalized economy was a pillar of the rules-based international order, and that trade and financial ties would prevent major powers from going to war. The United States helped bring China into the World Trade Organization in 2001 in order to bring its economic behavior in line with the West. Russia joined the organization in 2012

Mr. Putin's war and China's aggressive actions in Asia have challenged those notions.

The idea of the liberal international order was that economic interdependence would prevent conflict, according to the president of the Center for European Policy Analysis. Well, we have seen that is not true.

Putin's actions have shown us that the world we've been living in is not the world he or China have been living in.

The United States and its partners have banned transactions with the Russian central bank in order to keep Russia out of the international financial system. Russia has been cut off from the global bank messaging system called SWIFT, frozen the assets of Russian leaders and oligarchs, and banned the export from the United States and other nations of advanced technology to Russia. Russia has banned exports of food, cars and timber.

British and European sanctions on Roman Abramovich, the Russian billionaire who owns the soccer team in Britain, prevent the club from selling tickets or merchandise.

Some of the brands that have decided to suspend or withdraw operations from Russia include Apple, Ikea and Rolex.

Cracking down on dissent. A Russian court sentenced Navalny to nine years in prison for fraud after he was already sentenced for violating parole. The scope of government bodies off-limits to criticism has been amended by Russia.

Many countries still depend on Russian energy exports, and governments are trying to figure out how to wean themselves. Washington and London will stop imports of Russian oil.

The question is whether any of the U.S.-led penalties will be extended to China, which is more important to the global economy than Russia.

Mr. Biden has continued the policies of the Trump administration that aim to delink parts of the American economy from that of China and punish Beijing for its commercial practices.

About two-thirds of Chinese imports were subject to the tariffs. The Treasury Department imposes investment bans on Chinese companies with military ties. In June, a law will go into effect in the United States barring goods made in whole or in part of the region of Xinjiang.

Demand for Chinese-made goods has gone up despite all that. Last year, the U.S. trade deficit grew to a record level, as foreign investments into China increased.

Some economists want more global integration. Speaking at a virtual conference on Monday, the director general of the World Trade Organization urged a move toward re-globalization.

If the U.S.-China relationship gets worse, the economic ties will be strained even more.

The Commerce Department said it would ban the sale of American technology to Chinese companies if China tried to sell it to Russia.

The U.S.-China relationship is in a state of uncertainty. Foreign asset managers have begun moving their money out of China in recent weeks, possibly in anticipation of sanctions, as many major Chinese banks and private companies have suspended their interactions with Russia to comply with sanctions.

Mary Lovely, a senior fellow at the Peterson Institute for International Economics, said she did not expect China to throw all in with Russia, but that the war could still strain economic ties.

There is great uncertainty as to how the U.S. and China will respond to the challenges posed by Russia.
