The Macao SAR Government is highly concerned over reports of US Government's secret internet surveillance on many countries and regions, and wondered if it included Macao networks. The Chief Executive, Mr Chui Sai On, said he has expressed the concern when he met with Consul General of the United States in Hong Kong and Macao, at the reception to commemorate the 237th anniversary of the Independence of the United States of America. The SAR Government has been dedicating full efforts to safeguard Macao's freedom of information, personal privacy and network safety by applying effective measures to protect the government's internal network and data, Mr Chui said. Meanwhile, the Office for Personal Data Protection has sent a letter to the Consulate General of the United States in Hong Kong and Macao to ask for a clarification, and an explanation for the allegation.
