As trade disputes simmer, Chinese telecommunications giant Huawei, the No. 3 smartphone brand, is shifting its growth efforts toward Europe and Asia in the face of mounting obstacles in the U.S. market. Shenzhen-based Huawei, the world's largest maker of telecoms equipment, has long coveted access to the U.S. but recently laid off key American employees at its Washington D.C. office. The U.S. has regularly stymied Huawei's efforts to enter the America, citing national security concerns. Huawei has failed to find a U.S. carrier to partner with for its smartphones, and the Federal Communications Commission on Tuesday approved a draft order that could damage Huawei's existing business in network gear. The order cited Huawei and its Chinese rival ZTE by name. That came after Huawei canceled a planned January announcement that a major U.S. carrier would sell its smartphones for the first time. The company gave no details but news reports said that partner was AT&T Inc. and scrapped the deal under government pressure.

Huawei's struggles in the United States are in contrast to its booming business in developing countries and growing presence in Europe, where it has been working on next-generation, or "5G," wireless standards. The company's profits rose 28.1 percent in 2017, boosted by strong enterprise and consumer sales and booming business overseas. The recent setbacks have left Huawei's future in the U.S. uncertain. Huawei recently let go of several American employees in their Washington D.C. office, including William Plummer, who spearheaded efforts to convince the U.S. to allow Huawei in for nearly a decade. American companies have long chafed under Chinese regulations that require them to operate through local partners and share technology with potential competitors in exchange for market access.

Huawei and ZTE's burgeoning 5G research is seen as a particular threat, as its expanded transmitting capabilities are seen as crucial for a host of emerging technologies based on artificial intelligence - including self-driving vehicles, robots and other machines that transmit vast amounts of data in real time. ZTE faces devastating threats to its business after the U.S. Commerce Department blocked the company from importing American components for seven years, accusing the smartphone maker of misleading U.S. regulators after it settled charges of violating sanctions against North Korea and Iran. But unlike ZTE, efforts to impede Huawei in the U.S. likely won't stop its rapid expansion elsewhere. Last month, Huawei's president of consumer handsets Kevin Ho said the company is pivoting to Europe and developing Asian markets. He called them priorities "No. 1" and "No. 2." Huawei chose to unveil its latest flagship phone last month at the Grand Palais in Paris, while in Finland, the company employs more than 300 engineers developing cameras, audio algorithms, and 5G technology. Many used to work at Finnish rival Nokia.
