V. Read the passage. Việt Nam regrets the French court's decision to reject the lawsuit of Trân Tố Nga to report several multinational companies that produced and traded the toxic herbicide Agent Orange during the American war in Việt Nam. Việt Nam as a country has suffered devastating consequences of wars, including the long-lasting and serious impacts of Agent Orange/dioxin, spokesperson Hằng said. An estimated 4 million Vietnamese people have been exposed to AO/dioxin that the US military dropped in the central and southern region of Việt Nam to clear out forests where they thought northern soldiers could be hiding, while 100,000 children have suffered from deformities. Trần Tố Nga, a 79year-old woman with dual citizenship in Việt Nam and France, has been for the past decade seeking damages from the multinationals in recognition of severe chronic health issues as the result of exposure to the toxin. Nga said she would continue to file an appeal. Spokesperson Hăng noted that throughout the trial, the Vietnamese embassy in France has been keeping in contact with Nga and providing necessary support when appropriate.
