China warns new US port fees 'detrimental to all parties'

China warned Friday that new U.S. port fees on Chinese-built and operated ships would be "detrimental to all parties" as Washington seeks to boost its domestic shipbuilding industry and curb Beijing's dominance in the sector. "They drive up global shipping costs (and) disrupt the stability of global production and supply chains," foreign ministry spokesman Lin Jian said, adding, "They will not succeed in revitalizing the U.S. shipbuilding industry."
