Chinese telecom giant Huawei will release a 5G smartphone in June, the company’s rotating chairman Hu Houkun (also known as Ken Hu) said at the World Economic Forum in Davos on Tuesday.

Hu said Huawei has deployed 5G networks in 10 countries, with 20 more to come.

The news comes amid tough times for Huawei. Several countries have blocked the company from working on their sensitive network infrastructure, out of national security concerns. The company’s CFO, Meng Wanzhou, was arrested last month in Canada, at the request of the U.S., on charges related to violation of American sanctions on Iran.

Hu said that the pressure Huawei is feeling at the moment could be "the largest among related parties.”

Hu also said 2019 will be a crucial year for the tech sector, as technologies such as the internet of things, artificial intelligence, and blockchain are reaching critical application stages.
