US needs to share evidence about Huawei to see use of Chinese tech: Vodafone chief

The United States needs to share any evidence about Huawei with European authorities so they can take a common view about whether to use the Chinese group's technology in their networks, the head of Vodafone said on Monday.

Nick Read, chief executive of the world's second-largest mobile operator, told reporters in Barcelona on Monday that cutting the number of network suppliers to two from three would damage the industry and economic growth.

Huawei, the world's biggest producer of telecoms equipment, is under intense scrutiny after the United States told allies not to use its technology because of fears it could be a vehicle for Chinese spy operations.
