A decade ago, many Western brands viewed China as an opportunity.

 Today, China is becoming something else.

It runs more like a test or a proving ground... and increasingly, a market that operates on its own terms.

This week's China Pulse examines three developments that caught my attention because they challenge some of the assumptions many executives still hold about China.

A few highlights:

• SKIMS chose Hong Kong (not Shanghai) for its China debut, signaling that the traditional China entry playbook may be changing.

• Steph Curry signed with Li-Ning in a partnership that looks far more like a strategic alliance than a traditional endorsement deal.

• Lululemon's China business grew 30% while its Americas business declined, highlighting just how different consumer demand can be across markets.

Taken individually, these are interesting stories.

Taken together, they reveal something bigger.

China is becoming more confident, more competitive, and more capable of shaping outcomes rather than simply reacting to them.

Many executives are still operating from a version of China that no longer exists.

The question is whether they'll realize it before their competitors do.
