China's State Banks Change Strategy Amid Yuan Rally

Imagine China's banks are playing a currency game.

The Chinese currency, the yuan, has been getting stronger, which is good for people who want to buy things.

But it can also make it harder for China to sell things to other countries.

To slow down the yuan's rise, the banks are doing two things: selling yuan and buying dollars.

They're also offering dollars for yuan in a different market, which makes it more expensive to get dollars.

These moves are different from what they were doing before.

Now, experts are watching to see why they've changed their strategy.
