and 1990s. The revolutions of 1989 and subsequent liberalization in many parts of the world resulted in a significant expansion of global interconnectedness. The migration and movement of people can also be highlighted as a prominent feature of the globalization process. In the period between 1965 and 1990, the proportion of the labor force migrating approximately doubled. Most migration occurred between the developing countries and least developed countries (LDCs). As economic integration intensified workers moved to areas with higher wages and most of the developing world oriented toward the international market economy. The collapse of the Soviet Union not only ended the Cold War's division of the world – it also left the United States its sole policeman and an unfettered advocate of free market. It also resulted in the growing prominence of attention focused on the movement of diseases, the proliferation of popular culture and consumer values, the growing prominence of international institutions like the UN, and concerted international action on such issues as the environment and human rights. Other developments as dramatic were the Internet's becoming influential in connecting people across the world; , more than 2.4 billion people—over a third of the world's human population—have used the services of the Internet. Growth of globalization has never been smooth. One influential event was the late 2000s recession, which was associated with lower growth (in areas such as cross-border phone calls and Skype usage) or even temporarily negative growth (in areas such as trade) of global interconnectedness. The China–United States trade war, starting in 2018, negatively affected trade between the two largest national economies. The economic impact of the COVID-19 pandemic included a massive decline in tourism and international business travel as many countries temporarily closed borders. The 2021–2022 global supply chain crisis resulted from temporary shutdowns of manufacturing and transportation facilities, and labor shortages. Supply problems incentivized some switches to domestic production. The economic impact of the 2022 Russian invasion of Ukraine included a blockade of Ukrainian ports and international sanctions on Russia, resulting in some de-coupling of the Russian economy with global trade, especially with the European Union and other Western countries. Economic globalization Economic globalization is the increasing economic interdependence of national economies across the world through a rapid increase in cross-border movement of goods, services, technology, and capital. Whereas the globalization of business is centered around the diminution of international trade regulations as well as
