The agreement expands the China-Chile Smart Customs partnership through information sharing and enforcement coordination. Areas of cooperation include mutual recognition of Authorized Economic Operator status, clearance efficiency, enterprise credit, anti-smuggling and IP protection. Pan Chuxiong, deputy director of Shenzhen Customs, said Shenzhen maintains close economic and trade ties with Chile, with three direct shipping routes to major Chilean ports each week. In the first seven months of this year, trade between Shenzhen port and Chile reached 21.96 billion yuan (about $3.06 billion). More than 40% of Chile's cherry imports to China enter through Shenzhen. "The cooperation with Valparaíso Customs will further enhance cross-border trade facilitation and create new opportunities for bilateral trade in high-quality goods," Pan said.
