结对帮扶
pairing assistance

三十年来，我国持续实施结对帮扶，安排东部发达省市帮扶西部贫困地区，通过提供资金、技术和人才支持，推动全国区域协调均衡发展。
For three decades, China has implemented the pairing assistance program, a move that matches its more affluent eastern provinces and municipalities with less-developed western regions, delivering financial, technical and human resource support to foster more balanced national development.
