A top security official called for developed economies to increase technical assistance and intelligence sharing with developing economies to deal with cross-border corruption cases.

Speaking at an annual meeting of the International Association of Anti-Corruption Authorities, Meng Jianzhu, head of the Political and Legislative Affairs Committee of the Communist Party of China Central Committee, said those forms of cooperation are needed to effectively fight corruption.

Eliminating cross-border corruption is extremely difficult because of differences in economic development, and political and legal systems, as well as historical and cultural backgrounds, he said.
