中国投资为孟加拉经济注入新动力
Jing Ji Ri Bao· 2025-09-04 22:04
中国已连续15年成为孟加拉国第一大贸易伙伴,有近千家中国企业在孟经营。展望未来,中孟投资合作 有望从成衣和纺织品、基础设施、港口物流等传统领域向绿色能源、数字经济、电动汽车等领域拓展。 在制造业领域,成衣和纺织品等劳动密集型产业充分发挥孟加拉国的劳动力成本优势和关税优惠比较优 势,成为吸引中国投资的重点。美国政府对印度加征高额关税后,服装采购商纷纷转向孟加拉国供应 商。美国政府曾威胁对孟加拉国服装进口加征35%的关税,高于同处南亚地区的印度和巴基斯坦,但在 8月1日截止期限前,美国把对孟加拉国加征的"对等关税"降至20%,而对印度加征关税为25%,甚至可 能进一步提高到50%,使原来从印度采购的买家转至孟加拉国,孟加拉国服装制造商也抓住机遇,与中 国企业加强合作,重启扩建计划,并增资配套产业,中国投资正当其时。 在基础设施领域,中国企业重点参与了总投资4.12亿美元的达卡绕城高速公路项目,这是孟加拉国首条 全封闭高速公路,项目全长约48公里,连接达卡北部和东北部工业区,并串联多条国道,对孟加拉国道 路连通意义重大。项目首段18公里已于今年3月试运营,并于8月正式通车,有助于缓解首都达卡交通严 重拥堵问题,并激 ...
