１９９９年１１月底，辽宁轮胎集团公司全钢载重子午胎二期工程项目经考核符合合同标准，中外双方签署了验收合同。至此，该公司２０万套全钢子午胎生产线经过３５个月的建设，正式进入生产阶段。这项二期工程是在我国第一条引进的１５万套全钢载重子午胎生产线基础上兴建的。 At the end of November 1999, Liaoning Tire Group Corporation’s all-steel radial tire second-phase project was assessed to meet the contractual standards, and the Chinese and foreign parties signed the acceptance contract. At this point, the company’s 200,000 sets of all steel radial tire production line after 35 months of construction, formally entered the production phase. The second phase of the project was built on the basis of the first 150,000 sets of all-steel radial tire production lines introduced in China.
