Comment on "Beijing vows cleaner air" (China Daily, Jan 23)

A lot more has to be done to restore the environment. And clean air is the most important part of the environment. China has spent billions of yuan to prevent sandstorms. It has to spend even more to have cleaner air.

A truly great city must be clean and green. Stricter laws must be enforced to make Beijing a healthy place to live in. I hope Beijing catches up with other clean and green cities across the world. The road is tough but not impossible.
