A resource that rather surprised me:

Bhikkhu Dama et. al. (Transl.): A Chinese Translation of Buddhadatta's
'Concise Pali-English Dictionary'. Digital Version (Version 1.0).

http://sw.chibs.edu.tw/~mb/tools/paliChinDict/indexPaliChin.html

Other materials from the same author are listed here:

They include a reference utility for finding the Chinese Agama
translations/equivalents when working from Pali sources.
