Telecommunications-equipment manufacturer Huawei Technologies is restricting its business in Iran voluntarily, despite its business in Iran been in full compliance with all applicable laws and regulations including those of the UN, US and EU.

In an official statement, the company said that it is no longer seeking new customers and limiting its business activities with existing customers due to the increasingly complex situation in Iran. The statement comes in the wake of news that the Iranian authorities were using mobile networks to track dissidents.

For communications networks that have been delivered or are under delivery to customers, Huawei says it will continue to provide necessary services to ensure communications for Iran’s citizens.
