     Is it time to kick Russia out of the BRICs (金砖四国)? If so, it may end up sounding like a famous

ball-point pen maker-BIC. An argument is being made that Goldman Sach's famous marketing device

(策略), the BRICs, should really be the BICs.

     "Is Russia really worth the name BRICs?" asks Anders Aslund, senior fellow at the Peterson Institute

for International Economics, in an article for Foreign Policy. Aslund, who is also co-author with Andrew

Kuchins of  "The Russian Balance Sheet", thinks the Russia of Putin and Medvedev is just not worthy of

inclusion alongside Brazil, India and China in the list of future economic powerhouses. He writes:

     "The country's economic performance has fallen to such a weak level that one must ask whether it has

any say at all on the global economy, compared with the other members of its group. I have just returned

from Moscow, which is always dull around this season. For the last seven years, Russia has taken very

few measures to improve its economy. Instead, the state has been living on oil and gas."

     Economically, Aslund has the numbers on his side. The International Monetary Fund figures that the

Russian economy will fall by 6.7 percent in 2009, while China will grow 8.5 percent and India 5.4 percent.

There is less of a case for Brazil, with a fall of 0.7 percent, but it is still doing far better than Russia.

     But the BRICs are not just about economy. As is mentioned above, it is a marketing device to encourage

investors (投资者)to focus on the big promising players. From an investment standpoint, it could be argued

that Russia is leading the BRICs. Its stock (股票) market is up 128 percent this year while around 80 percent

is for the other three.

     At very least, however, Russia's economic underperformance and stock market outperformance does suggest it is indeed one of the group.
