     When I was going home to India last year, I called up my mother to ask if she wanted anything from

China.

     When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and

jeans. Thankfully, we can get all these anywhere in India now. 

     Still, her answer surprised me: "Green tea."

     As long as I can remember she didn't even drink Indian tea. 

     I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her

brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all

illnesses.

     At the turn of the century, China was not really familiar to the average Indian. It was a strange

country. 

     How things change! And how soon! Now every town of any size seems to have a "China Market".

And everyone is talking about China. The govemment of Indin has planned to send a team to China to

see how things are done. A minister once said that India must open the doors for more foreign

investment (投资) and such a step would "work wonders as it did for China". 

     But it's a two-way street. I just heard about a thousand Shenzhen office workers who have gone

to Bangalore to train in software. Meanwhile, all the Indian IT majors are setting up a strong presence

in China. 

     No wonder that trade, which was only in the millions just ten years ago, is expected to hit about

US $15 billion for last year and US $20 billion by 2008, a goal set by both governments. No wonder,

my colleague wrote some weeks ago about this being the Sino-Indian (中印) century as the two

countries started on January 1 the Sino-Indian Friendship Year. But what is still a wonder to me is

my mother drinking Chinese tea.

1. The reason why the writer's mother asked for Chinese green tea is that _____.[ ]

A. The exchanges between Indian and China benefit both

B. China and India have different traffic rules
