The Second Pacific Rim Mathematical Association (PRIMA) Congress was held in Shanghai, China, June 24-28, 2013. With more than 800 registered participants from around the world, the conference was the second biggest mathematical event that ever took place in China (second only to the International Congress of Mathematicians (ICM) held in Beijing, China, August 20-28, 2002).

Highlights of the conference were 2 public lectures, given by Ronald Graham (University of California, San Diego) and Cédric Villani (Université de Lyon and Institut Henri Poincaré). There were also 11 plenary lectures and 23 special sessions.

The special session on Combinatorics and Discrete Mathematics consisted of 22 lectures covering the frontier of many research areas, presented by the following invited speakers:

Eiichi Bannai (Shanghai Jiao Tong University), Andreas Brandstädt (University of Rostock), David Bryant (University of Otago), L. Sunil Chandran (Indian Institute of Science), Nikolai Dolbilin (Steklov Mathematical Institute), Andreas Dress (Chinese Academy of Sciences), Stefan Grünewald (Chinese Academy of Sciences), Michel Habib (University Paris Diderot Paris 7), Pinar Heggernes (University of Bergen), Pavol Hell (Simon Fraser University), Jing Huang (University of Victoria), Jan Kratochvíl (Charles University), Jack Koolen (University of Science and Technology of China), Brendan McKay (Australian National University), Jaroslav Nešetřil (Charles University), Sang-il Oum (Korean Advanced Institute of Science and Technology), Bruce Reed (McGill University), Moshe Rosenfeld (University of Washington Tacoma), Jayme L. Szwarcfiter (Universidade Fed. do Rio de Janeiro), Mikhail Tyaglov (Shanghai Jiao Tong University), Ryuhei Uehara (Japan Advanced Institute of Science and Technology), Xuding Zhu (Zhejiang Normal University).

This special issue of Discrete Mathematics & Theoretical Computer Science collects papers related to work that was presented at this special session and in some further pertinent contributions. We would like to thank all participants (invited speakers, authors, and anonymous referees) for their presence and contribution.
