In statements to the Hong Kong and Shenzhen stock exchanges, ZTE said trading in its shares had been halted at its request over the "United States Commerce Department's proposal to implement export restrictions on the company" but gave no further details.
ZTE is China's second-biggest telecom equipment maker. News agency Reuters reported that the restrictions mean ZTE's suppliers must apply for an export licence before shipping any US-made equipment or parts to the Chinese company.
The report, which quoted documents and a senior official at the US Commerce Department, said the measures will take effect on Tuesday.
Asked about the issue, China's foreign ministry on Monday criticised US government actions against the country's companies. "China is always opposed to US sanctions on Chinese enterprises citing domestic laws," foreign ministry spokesman Hong Lei told reporters in Beijing.
"We hope that the US side can stop such erroneous practices so as to avoid further damage to Sino-US economic cooperation and bilateral relations."

Washington in January eased several restrictions on doing business with Iran, following an international agreement over the country's nuclear programme. But sanctions tied to accusations that Tehran supports terrorism remain in effect, still largely blocking US companies from business with Iran.
