China's grand bet is on green technology and these electric vehicles.

Globally the scale is staggering.

More than half of all new EVs sold worldwide are from China.

It makes them cheaper and can build them faster than its competitors.

But there's a catch.

These cars are causing growing trade tension between China on one side and the US and Europe on the other.

China is accused of flooding the global market, producing more cars than there are buyers.

And companies in the West are worried they can't compete.

At Beijing's auto show, raw rivalry on display.

And the buzz all about the latest EV models.

High tech, high end.

Company bosses treated like rock stars.

It takes two seconds from zero to 100 kilometres per hour.

As foreign firms set up EV plants in China, Chinese companies looked on and learned fast.

Now they've caught up.

Definitely yes.

The performance, the design, everything, the culture.

What's your message to the leaders of those countries about Chinese electric vehicles dominating the market?

I think I would not say it's dominating the market.

I would say it's just to bring more diversity to the local customer.

It's a natural competition.

This year China expects to make 11 million electric vehicles.

Yeah, it's going to be very hard to beat them.

They've got incredible resources from the government, etc.

And they're obviously creating jobs and making sure they've actually got a good economy to build on.

But you say the rest of the world can't compete with China?

No, no.

No chance?

No chance.

No.

German car companies face fierce competition.

Last week its chancellor walked a fine line on the debate over EVs.

Do you agree with the EU and US position that China is dumping cheap green technology products on the global market?

It's clear that we have to talk about questions of overcapacity and that we have to talk about subsidy competition.

This is an important topic because there are subsidies all over the world.

Many countries are doing it when it comes to renewable energies and advanced e-mobility technologies.

That's why it's important that we establish rules that prevent everyone from continuing as they wish.

Rules aside, here is unbridled ambition to lead the world in batteries, solar panels and EVs.

All part of President Xi Jinping's plan to overhaul the country's debt-driven economy.

Creating cars at cutthroat prices.

China's competitors are watching nervously.
