Is there a big difference in weather between Algeria and China?

China? This range is too big, a south and a north, a world of difference.

Let's just say that the coastal area of Algeria has a typical Mediterranean climate, which is similar to that of southern France. It's not cold in winter and not hot in summer, which is very comfortable. There is no such weather in China.

In the south, inland, is the Sahara desert. I think deserts all over the world are similar. Just go to the Taklimakan Desert in Xinjiang and have a look.
