China calls for Switzerland to increase production of medical supplies and work with China to guarantee the materials needed in combating the COVID-19 and ensure the stability of global industrial and supply chains, a senior official said. State Councilor and Foreign Minister Wang Yi made the remarks in a telephone conversation with Swiss Foreign Minister Ignazio Cassis. China is speeding up production of ventilators, which are the most urgently-needed equipment, Wang said. He said China hopes Switzerland, one of the world’s major suppliers of ventilators parts, will increase production to meet the pressing demands of the world. China also would like to cooperate with Switzerland in researching and developing drugs and vaccines, Wang added. The State Councilor noted China has established a green channel to facilitate the transportation of supplies for pandemic prevention. China appreciated Switzerland for supporting the country in the fight against the novel coronavirus, he said, adding that the Swiss embassy and consulates in China lowered flags to half-mast as China mourned those sacrificed and succumbed to the COVID-19 on Tomb Sweeping Day, which showed the friendship of Swiss people to the Chinese people.
