isn't china #1 already ?
No, why would they be? China is heavily depending on exports. Once they are getting close to surpass USA and Europe there will likely be a shift against cheap production from China. China can only grow if the world is helping them by buying their products. Once there is a harder stand against the expansionary foreign policy of china against their neighbours we will likely see lower growth rates.
That is why this country has started to target third-world countries and the middle east (excluding India). Many arrangements have been made so as to increase the exports and also for future purposes. They see that the US international regulations and sanctions weakened them and force the allies to stop trading with China
They are looking for new markets in Africa and UAE, too. Russia remains its supporters for many years.
Even though I do not like China, I have to admit that they are really really good at controlling society with more than 2 billion citizens. There have been many achievements so far and the level of developments are outstanding
