Li Kuiwen, spokesman of the General Administration of customs and director of the statistics and analysis department, said that due to the rebound of overseas epidemic, some overseas ports were indeed seriously congested, the international logistics supply chain was not smooth, and the ship operation efficiency and empty container turnover rate decreased significantly, resulting in the tension of relevant route capacity and the imbalance between supply and demand. But he also said that the relevant departments have done a lot of work recently, which has alleviated the tension of transportation capacity to a certain extent.
