A new U.S. rule regarding China's Huawei Technologies Co. Ltd. is a needed "clarification" to help develop standards, U.S. Commerce Secretary Wilbur Ross said on Wednesday, adding that security concerns remain over the telecoms equipment maker.

Ross, in an interview on Fox Business Network, said the rule released by the department on Tuesday would help create uniformity, but that the United States was still concerned about the potential for spying and opposed the use of Huawei technology in 5G networks.

"The change is really simply a clarification. It isn't that we're doing something to help Huawei. What we're doing is something to make it easier for global standards to be symmetrical," he said.

"This is to help make sure we have ubiquity in 5G," Ross added.

"This is not to help Huawei," Ross said .

Ross said the U.S. is still opposed to the use of Huawei technology in 5G and 4G networks and maintained that spying is a real concern.

"We are very opposed to the use of Huawei, 4G, 5G. We’ve been explaining our purposes to countries all around the world and they’re gradually getting to realize it," he said. "There really is a vulnerability with 5G t

The rule, scheduled to be formally published on Thursday, amends the Huawei "entity listing" that restricts sales of U.S. goods and technology to the company to allow the release of certain technology to Huawei and its affiliates if it contributes "to the revision or development of a 'standard' in a 'standards organization.'"

The United States had placed Huawei on the entity list in May 2019, citing national security concerns, and Ross on Wednesday said those concerns remain especially over 5G.

"The spying is very real issue," Ross told the television network.
