The California-based firm produces some of the world's most advanced semiconductors but is not allowed to ship its most cutting-edge chips to China owing to concerns that Beijing could use them to boost its military capabilities.

It developed the H20 -- a less powerful version of its AI processing units -- specifically for export to China, although that plan hit the skids when the Trump administration firmed up export licence requirements in April.

The company said in a statement on Tuesday that it was "filing applications to sell the Nvidia H20 GPU again".

"The US government has assured Nvidia that licences will be granted, and Nvidia hopes to start deliveries soon," the statement said.

Nvidia CEO Jensen Huang said in a video published by Chinese state broadcaster CCTV on Tuesday that "the US government has approved for us (to file) licences to start shipping H20s, and so we will start to sell H20s to the Chinese market".

"I'm looking forward to shipping H20s very soon, and so I'm very happy with that very, very good news," Huang, wearing his trademark black leather jacket, told a group of reporters.

Zhang Guobin, founder of the Chinese specialist website eetrend.com, said the resumption would "bring (Nvidia) substantial revenue growth, making up for the losses caused by the previous ban".

It would also ease the impact of trade frictions on the global supply chain for semiconductors, he told AFP.

But he said Chinese firms would remain focused on domestic chip development, adding that "the Trump administration has been... prone to abrupt policy shifts, making it difficult to gauge how long such an opening might endure".

Huang will attend a major supply chain gathering on Wednesday, the event organiser confirmed to AFP.

It will be his third trip to China this year, according to CCTV.

- 'Positive role' -

China is a crucial market for Nvidia but in recent years the US export squeeze has left it battling tougher competition from local players such as homegrown champion Huawei.

Beijing has decried Washington's curbs as unfair and designed to hinder its development.

Huang, an electrical engineer, told Chinese Vice Premier He Lifeng on a visit to Beijing in April that he "looked favourably upon the potential of the Chinese economy", according to state news agency Xinhua.

He said he was "willing to continue to plough deeply into the Chinese market and play a positive role in promoting US-China trade cooperation", Xinhua reported.

The tightened US export curbs have come as China's economy wavers, with domestic consumers reluctant to spend and a prolonged property sector crisis weighing on growth.

President Xi Jinping has called for China to become more self-reliant as uncertainty in the external environment increases.

The Financial Times reported in May that Nvidia was planning to build a research and development centre in Shanghai. Neither Nvidia nor the city's authorities confirmed the project to AFP at the time.

China's economy grew 5.2 percent in the second quarter of the year, official data showed on Tuesday, after analysts predicted strong exports despite trade war pressures.
