我国成为世界贸易组织(WTO)成员,必然要兑现承诺关税减让义务。我国以发展中国家身份加入WTO,应该承担相应的权利和义务,关税减让不是一步到位,有一个过渡期。从今年1月1日起,我国就开始履行加入WTO承诺的2002年关税减让义务,海关总署调整了《中华人民共和国海关进出口税则》,关税算术水平由15.3％降低到12％, As a member of the World Trade Organization (WTO), our country will inevitably honor its obligation to impose a tariff reduction concession.

Starting from January 1 this year, China began to fulfill its duties of tariff concession in 2002 as promised by accession to the WTO.
