This codebook outlines the set of TUFF procedures that
have been developed, tested, refined, and implemented by AidData staff and
affiliated faculty at the College of William & Mary. We initially employed
these methods to achieve a specific objective: documenting the known universe
of officially financed Chinese projects in Africa (Strange et al. 2013, 2017). We
have since then employed these methods to track Chinese official finance to
five major world regions: Africa, the Middle East, Asia and the Pacific, Latin
America and the Caribbean, and Central and Eastern Europe (Dreher et al. 2017).
Additionally, other social scientists have adapted and applied the TUFF
methodology to identify grants and loans from Gulf Cooperation Council (GCC)
members (Minor et al. 2014), under-reported humanitarian assistance flows from
traditional and non-traditional sources (Ghose 2017), foreign direct investment
from Western and non-Western sources (Bunte et al. 2017), and pre-2000 foreign
aid flows from China (Morgan and Zheng 2017). However, this codebook focuses
specifically on TUFF data collection and quality assurance procedures to track
Chinese official finance between 2000 and 2014.
