Chinese telecoms giant expects revenue growth to slow down in 2020 as US sanctions take their toll.

China's Huawei Technologies has said on Tuesday that its full-year revenue would likely jump 18 percent in 2019 to 850 billion yuan ($122bn), lower than its earlier projections, as a trade blacklisting by the United States curbed growth and disrupted its ability to source key parts.

The world's biggest maker of telecom network equipment and the No 2 manufacturer of smartphones, was all but banned by the US in May from doing business with US companies, preventing its access to technology like Google's Android operating system.

The US government alleges Huawei equipment poses national security risks because it could be used by the Chinese government to spy on users. Huawei has repeatedly denied its products are a security threat.

Huawei's Rotating Chairman Eric Xu revealed the numbers in a New Year's message to employees and customers in which he also forecast 2020 to be a "difficult year", saying the firm was unlikely to grow as rapidly as it did in the first half of this year.

"Survival will be our first priority" in 2020, said Xu.

Its 18-percent revenue growth forecast for 2019 is less than that of 2018, when Huawei's annual revenue rose 19.5 percent.

The company did not break down fourth-quarter figures but, according to Reuters calculations based on its previous statements, revenue in the quarter to end December 31 rose to 239.2 billion yuan ($23.3bn), up 3.9 percent from a year earlier and slower than the 27 percent increase it reported in the third quarter.

"The external environment is becoming more complicated than ever, and downward pressure on the global economy has intensified," Xu said.
