This is a customs notice at the transit centre in the Guangzhou Airport. Normally this used to be just in Chinese and English back in 2018. But now it’s in Chinese, English, Korean, Japanese, French, Spanish, Arabic and in one more language. It definitely shows that China is trying to be more international with its overseas visitors. I do see a reciprocity in the Melbourne airport as they run public safety announcements in Mandarin (and Hindi) regularly. But other than that, everything else is pretty much in English only.
