Any act of privately collecting intelligence from other countries without legal procedures and authorization is illegal and seriously violates the basic norms and ethical standards of international relations. It must not be allowed, no matter what the banner is. Countries should communicate and cooperate in a peaceful, legal, equal and mutually respectful manner. This kind of private and illegal intelligence collection will not only undermine the trust and cooperation between countries, cause diplomatic disputes and tensions, but may also lead to serious legal consequences and damage the country's international image and reputation. Maintaining national interests should be achieved through legal, legitimate and standardized channels and methods, relying on diplomatic efforts, international cooperation, self-development and other positive means, rather than taking illegal and irregular actions. We must always act within the framework of law and morality and jointly promote the stability and harmony of the international order.
