Our colleague Lingling Wei is the chief China correspondent for The Wall Street Journal.
And lately, she's had to learn a lot about tech, specifically semiconductor chips.
I'm getting a crash course over chips.
Seriously, I'm really fascinated myself.
In particular, Lingling has been reporting on one tech CEO.
Jensen Huang.
Jensen Huang is the CEO of NVIDIA, a California-based chip designer.
NVIDIA is the most valuable company in the whole world right now,
with a market capitalization of over $4 trillion.
NVIDIA chips power some of the biggest AI models in the world.
And as the company has become more important in the race for artificial intelligence,
It's also found itself in the middle of a tense trade battle between the U.S. and China.
Lingling says that's meant a new role for the tech company's CEO.
Huang, for many years, he had largely avoided the rough and tumble world of politics in Washington.
He mostly delegated the messy task of lobbying to some of his key underlings.
That started to change after Trump won the election late last year.
Huang has been busy lobbying both Washington and Beijing.
Now, he's looking at a massive deal for his company, worth billions of dollars.
The deal could reshape how companies navigate business with the U.S. government,
and it's transformed the NVIDIA CEO into a major player in geopolitics.
