Chinese leader Xi Jinping on Tuesday urged political parties worldwide to oppose any country that engages in "technology blockades," an allusion to the United States, which views China as its strategic competitor.

As U.S. President Joe Biden's administration has sought support from like-minded democracies including the European Union and Japan to coordinate a tougher stance against China, Beijing has doubled down on seeking support and affirmation from friendly nations such as North Korea and Serbia.

"Together, we must oppose all acts of unilateralism in the name of multilateralism, hegemony and power politics," Xi told a virtual gathering of representatives of 500 parties from 160 countries such as Russia, Zimbabwe, Cuba and Burkina Faso.
