President Donald Trump agreed at a meeting with the heads of top technology companies like Google on Monday to make "timely" decisions on requests by US companies to sell to blacklisted Huawei Technologies Co Ltd, the White House said.

But even as the CEOs of the companies "requested timely licensing decisions from the Department of Commerce," the White House said in a statement that the executives expressed "strong support" for national security restrictions on US telecom equipment purchases and sales to Huawei.

The meeting, previously reported by Reuters, was with the CEOs of Cisco, Intel Corp, Broadcom Inc, Qualcomm, Micron Technology Inc, Western Digital and Alphabet Inc.

The meeting comes at a time of lingering uncertainty over the future of US companies' ties to Huawei, the world's largest telecommunications equipment maker. 

It was placed on a US blacklist in May, with the government citing national security concerns.

US companies were banned from selling most US parts and components to Huawei without special licenses. But Trump said last month that sales could resume as he sought to restart trade talks with Beijing.

Clarity on what the new policy toward Huawei will be has been slow to emerge.

On Monday, executives expressed displeasure at Commerce Department Secretary Wilbur Ross, who also attended the meeting, for not providing clear guidelines on policy toward sales to the Chinese company, according to a person briefed on the meeting. 

White House economic adviser Larry Kudlow and Treasury Secretary Steven Mnuchin were also at the meeting, the person said.

Ross has said licenses would be issued where there is no threat to national security. 

Reuters reported last week that the United States could approve licenses for companies to restart new sales in a matter of weeks.

However, the Washington Post reported on Monday that Huawei secretly helped North Korea build and maintain its commercial wireless network.

That may bolster China hawks in the US government who see Huawei as a national security risk, over those who seek a more lenient policy to appease Beijing amid ongoing trade talks between the world's two biggest economies.

The United States accuses Huawei of violating Iran sanctions and stealing American intellectual property, accusations Huawei denies. 

Washington has also lobbied allied governments to keep Huawei out of their 5G networks, arguing that the company's equipment could be used to spy for the Chinese government.

The White House said unfair international trade practices and 5G technology was also discussed at the event on Monday.
