So, Global Times welcomes the Prime Minister. It's an unsigned editorial, and therefore from within ther wider People's Daily borg, maybe from the tabloid version Huanqiu Shibao. Actually, I wouldn't be susprisied if Big Hu, the editor of both GT and HS, wrote it. Excerpts:
Perhaps there is no need to talk about "sincerity" in terms of Sino-British relations. What Cameron does is out of his own political interest and the UK's national interest. His visit this time can hardly be the end of the conflict between China and the UK.
Beijing needs to speed up the pace of turning its strength into diplomatic resources and make London pay the price for when it intrudes into the interests of China...
...The UK, France and Germany dare not make joint provocations toward China over the Dalai Lama issue.
... Chinese people believe that if London interferes in Hong Kong's transition process of implementing universal suffrage, Sino-British ties can be halted again.
The Cameron administration should acknowledge that the UK is not a big power in the eyes of the Chinese. It is just an old European country apt for travel and study. This has gradually become the habitual thought of the Chinese people.
...aaaand, the punchline!
Finally, let us show courtesy to Cameron and wish him a pleasant trip.
