This is an excerpt from a news article. What confuses me is the tense used in the first sentence. The simple past was used in the main clause while the present perfect in the subordinate, which, from what I learned, conflicts with general grammar rules. Is this a kind of exception because of 'emphasis on immediacy,' which is one of the features in news writing?
Korean state media Yonhap reported yesterday (March 2) that China’s national tourism administration has told travel agencies to stop selling group packages and offering free trips from Beijing to South Korea. Since July, relations between Beijing and Seoul have been icy after South Korea agreed to let the US deploy an antimissile system, a move China strongly opposes.
