In the twenty-first century the balance of world economic growth has shifted from the G7 industrialized economies, led by Europe, Japan, and the United States, to the emerging economies of Asia, especially China and India. While world growth will continue at a rapid pace, members of the G7 will grow more slowly than the world economy, while China and India will grow more rapidly. Growth in the advanced economies will recover from the financial and economic crisis of the past decade, but a longer-term trend toward slower economic growth will be re-established
