My hon. Friend is absolutely right to raise this point. The United Kingdom prides itself on the rule of law, a rules-based system and consistency, and that will remain the case, and of course we will welcome Chinese investment and investment from around the world. What has changed here are the US sanctions, and, as a result of those sanctions, we can no longer rely on Huawei equipment. Therefore, it is in the national interest to introduce this ban on new purchases from the beginning of the year.
