Actively is putting it lightly. They are aggressively seeking trade deals and investment opportunities. Especially since they use those to further their foreign policy aims.
The geopolitical implications of Trump's isolationist position is going to be significant.
Do you have an example where China implemented a trade agreements that resulted in significant trade balance surplus for the trading partner? (aside from energy)
New Zealand has a trade surplus with China. NZ was in the TPPA, but already have a FTA with China. They were trying for one with the US, but the US preferred the TPPA. [1][2]
Since the China FTA came into effect, China has replaced the US as NZ's number 1 trading partner. The US is 4th on that list.[3]
OK I stand corrected Energy and Food but New Zealand is definitely more an exception then a norm. We are running close to 400b trade deficit with China.
China has been doing some pretty complex deals with countries all across Africa - financing and building hydroelectric dams and other massive infrastructure buildouts. These are long-term deals that often include concessions for oil or other natural resources, so it's difficult to pin them down to a clear surplus/deficit.
Generally in such deals Chinese companies are the contractors doing the work and suppliers of goods, so again outside of energy I don't think China implemented any agreements that provided surplus for the trading partner.
