BEIJING - China's economic growth is poised to slow this year, with several leading economic indicators, including the PMI, dipping in the first half.

However, economists say the lower growth rates, despite making some investors jittery, are a welcome sign that Beijing's leaders are more focused on the quality and endurance of the economy than the previous heady growth targets.

They say China's growth, albeit slower, is still very robust compared to the world's other economies.

In an update of its World Economic Outlook issued in April, the International Monetary Fund projected the world economy would grow at 3.1 percent this year.

It forecast China's growth at 7.8 percent, much higher than the 5 percent forecast for emerging markets and developing economies as a whole, and the 2 percent growth for Japan, the United States and Europe.

British economist Jim O'Neill, best known for coining the "BRICs" acronym, pointed out that China's economy was now more than half the size of the United States, which meant "if China grows by 7.5 percent ... this would be equivalent of the US growing by 4 percent."

China's growth rate and its wealth-creating potential still stands out against other major economies in the world, and it will remain a key engine for world economic recovery from a middle and long term perspective.

According to O'Neill's estimate, if China grows by 7.5 percent annually in the next decade, it would be an economy of around $16 trillion or more by 2020, allowing its GDP per capita to reach $12,000-13,000.

China's current economic cooling stems from policy adjustments the government has rolled out, with an aim to deepen reform and lay foundations for future solid growth.
