（三）贸易畅通

贸易畅通是共建“一带一路”的重要内容。共建“一带一路”促进了沿线国家和地区贸易投资自由化便利化，降低了交易成本和营商成本，释放了发展潜力，进一步提升了各国参与经济全球化的广度和深度。

3. Unimpeded trade

Unimpeded trade is an important goal of the Belt and Road Initiative. The efforts invested in the initiative have liberalized and facilitated trade and investment in the participating countries and regions, lowered the costs of trade and business, and released growth potential, enabling the participants to engage in broader and deeper economic globalization.

1．贸易与投资自由化便利化水平不断提升。中国发起《推进“一带一路”贸易畅通合作倡议》，83个国家和国际组织积极参与。海关检验检疫合作不断深化，2017年5月首届“一带一路”国际合作高峰论坛以来，中国与沿线国家签署100多项合作文件，实现了50多种农产品食品检疫准入。中国和哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦农产品快速通关“绿色通道”建设积极推进，农产品通关时间缩短了90%。中国进一步放宽外资准入领域，营造高标准的国际营商环境，设立了面向全球开放的12个自由贸易试验区，并探索建设自由贸易港，吸引沿线国家来华投资。中国平均关税水平从加入世界贸易组织时的15.3%降至目前的7.5%。中国与东盟、新加坡、巴基斯坦、格鲁吉亚等多个国家和地区签署或升级了自由贸易协定，与欧亚经济联盟签署经贸合作协定，与沿线国家的自由贸易区网络体系逐步形成。

1) Greater liberalization and facilitation of trade and investment. China has issued the "Initiative on Promoting Unimpeded Trade Cooperation Along the Belt and Road", to which 83 countries and international organizations have subscribed. Cooperation in border inspection and quarantine has deepened. Since the first Belt and Road Forum for International Cooperation in May 2017, China has signed more than 100 cooperation agreements with other B&R countries, granting access to some 50 types of agricultural products and food after inspection and quarantine. Express customs clearance services for agricultural products between China and Kazakhstan, Kyrgyzstan, and Tajikistan have reduced the clearance time by 90 percent. China has further expanded sectors accepting foreign investment to create a business environment of high international standards. It has opened 12 pilot free trade zones for global business and experimented with free trade ports to attract investment from participating countries of the Belt and Road Initiative. China's average tariffs have dropped from 15.3 percent when it joined the World Trade Organization to 7.5 percent today. China has signed or upgraded free trade agreements with ASEAN, Singapore, Pakistan, Georgia and other countries and regions, and signed an economic and trade cooperation agreement with the Eurasian Economic Union. A network of free trade areas involving China and other B&R countries has taken shape.
