IP Tango that on August 1, 2011, two Free Trade Agreements (FTAs) entered into force: between Peru and Korea and between Costa Rica and China. Let's focus on the latter.
Professor López-Tarruella Martinez writes: "The FTA between Costa Rica and China includes specific provisions on generic resources, traditional knowledge and folklore and on geographical indications apart from general obligations to comply with TRIPS and Doha Declaration on Public Health, and on technical cooperation. There is a provision on border measures as well." You can find them in articles 109-117 of Chapter 10 Intellectual Property. Read the IP Tango article here.
So now China has the following three FTAs in the Western Hemisphere:
Costa Rica (2011)
Peru (2009), see here
Chile (2005), see here.
