China bemoans US 'bullying' of Huawei

China's foreign minister has slammed US moves against telecom giant Huawei as "economic bullying", and warned that Beijing was ready to "fight to the very end" in its trade war with Washington.

The trade spat between the world's top two economies escalated after President Donald Trump issued orders on grounds of national security last week that have prompted several foreign firms to distance themselves from Huawei.

"The US use of state power to arbitrarily exert pressure on a private Chinese company like Huawei is typical economic bullying," Foreign Minister Wang Yi said Wednesday at a meeting in Kyrgyzstan of the Shanghai Cooperation Organisation (SCO), a regional security group led by Beijing and Moscow.

Trump's move effectively bans US companies from supplying Huawei and affiliates with critical components over activities the US says are contrary its national security or foreign policy interests.

Japan's Panasonic announced on Thursday that it was cutting back business with Huawei in light of the US ban. A day earlier, mobile carriers in Japan and Britain said they would postpone the release of Huawei smartphones.

"Some people in the United States do not want China to enjoy the legitimate right to develop, and seek to impede its development process," Wang said, according to a foreign ministry statement issued late Wednesday.

"This extremely presumptuous and egocentric American approach is not able to gain the approval and support of the international community."
