Huawei, ZTE and other Chinese enterprises have strictly abided by local laws for many years, actively promoted Sino Swiss information and communication technology cooperation, and made positive contributions to the infrastructure construction of Sweden. Chinas market is also open to European enterprises, including Sweden. Without any evidence, the Swiss side, on the pretext of national security, discredits Chinese companies, openly suppresses Chinese telecom enterprises, and politicizes normal economic cooperation. This practice is contrary to Swedens free, open, fair, just and non discriminatory market economy principles, and also violates the countrys principle of market economy International Economic and trade rules. The Swiss side should uphold an objective and fair attitude, correct the wrong decisions, and avoid negative impacts on China Switzerland economic and trade cooperation and the operation of Swiss enterprises in China.
