In his first letter to employees in 2019, Huawei CEO Ren Zhengfei said the company will strengthen the credibility of its products largely by advancing Huawei’s software engineering.

Not the most moving of holiday letters, admittedly. But Ren is not prone to flowery language.

Ren said an initial $2 billion will be allocated toward engineering high-quality and “credible” telecom infrastructure products — saying the enhancement of its offerings would be “revolutionary.”

Huawei may count 2018 as the year it wished it could forget. Several countries banned Huawei’s involvement on telecom projects over national security and privacy concerns. And last month Canada arrested Huawei CFO Meng Wanzhou at the request of the U.S., who says she committed fraud in breach of U.S. sanctions against Iran.

Ren didn’t directly address these developments in letter, but he promised a focus on privacy.

“Cyber security and privacy protections will be our highest guiding principle,” he said. Credibility is a basic condition on which clients will be willing to buy Huawei products, he said, and for which governments will accept and trust Huawei.
