BEIJING — Chinese telecom giant Huawei Technologies said that its sales rose about 18% in 2019 despite U.S. moves to restrict its business.

The estimate came in an annual New Year’s message to employees from chairman Eric Xu.

The letter predicted a difficult year in 2020, saying that the American pressure creates a challenging environment for Huawei.

The U.S. government says Huawei technology poses a security risk and has urged other countries not to buy its 5G mobile network equipment. Huawei denies the allegations.

The unlisted company estimated annual sales would top $120 billion.
