High- and medium-high-technology manufacturing accounts for significant shares of exports from Ireland, Japan and Switzerland (shares of over 75%) as well as from Germany, Hungary, Korea and the United States. Among the BRIICS (Brazil, Russia, India, Indonesia, China and South Africa), these industries' exports are most important in China and Brazil, accounting for 55 and 32%, respectively, of total exports of manufactured and primary products. Because of the globalisation of value chains, a economy such as China imports more high-technology goods than it exports; much of these imports are components that are assembled in Chinese factories.
