Two World Health Organization experts are heading to the Chinese capital on Friday to lay the groundwork for a larger mission to investigate the origins of the coronavirus.An animal health expert and an epidemiologist will meet Chinese counterparts in Beijing to set the “scope and terms of reference” for a WHO-led international mission aimed at learning how the virus jumped from animals to humans, a WHO statement said.Scientists believe the virus may have originated in bats and was transmitted to another mammal such as a civet cat or an armadillo-like pangolin before being passed on to people.A cluster of infections late last year focused initial attention on a fresh food market in the central Chinese city of Wuhan, but the discovery of earlier cases suggests the animal-to-human jump may have happened elsewhere.In an effort to block future outbreaks, China has cracked down on the trade in wildlife and closed some markets, while enforcing strict containment measures that appear to have virtually stopped new local infections.The WHO mission is politically sensitive, with the U.S. — the top funder of the U.N. body — moving to cut ties with it over allegations it mishandled the outbreak and is biased toward China.“China took the lead in inviting WHO experts to investigate and discuss scientific virus tracing,” Chinese foreign ministry spokesperson Zhao Lijian said Friday.In contrast, he said, the U.S. “not only announced its withdrawal from the World Health Organization, but also politicized the anti-epidemic issue and played a buck-passing game to shift responsibilities.”More than 120 nations called for an investigation into the origins of the virus at the World Health Assembly in May. China has insisted that WHO lead the investigation and for it to wait until the pandemic is brought under control. The U.S., Brazil and India are continuing to see an increasing number of cases.The last WHO coronavirus-specific mission to China was in February, after which the team’s leader, Canadian doctor Bruce Aylward, praised China’s containment efforts and information sharing. Canadian and American officials have since criticized him as being too lenient on China.An Associated Press investigation showed that in January, WHO officials were privately frustrated over the lack of transparency and access in China, according to internal audio recordings. Their complaints included that China delayed releasing the genetic map, or genome, of the virus for more than a week after three different government labs had fully decoded the information.Privately, top WHO leaders complained in meetings in the week of Jan. 6 that China was not sharing enough data to assess how effectively the virus spread between people or what risk it posed to the rest of the world, costing valuable time. 2810

Twitter says it will begin removing misinformation about COVID-19 vaccinations from its site. That includes false claims that the virus is not real, debunked claims about the effects of receiving the vaccine. It will also remove baseless claims suggesting immunizations and vaccines are used to intentionally cause harm or to control people. Twitter said in a blog post on Wednesday that it will start enforcing the new policy next week. If people send tweets in violation of the rules, they will be required to delete them before they are able to tweet again. Before the offending tweet is removed, Twitter will hide it from view.Starting early next year, Twitter said it may label tweets that advance "unsubstantiated rumors, disputed claims, as well as incomplete or out-of-context information about vaccines" but may not be removed, instead be linked to "authoritative public health information" on the social media company's rules page that'll "provide people with additional context and authoritative information about COVID-19." 1043

TVs. Dishwashers. Printers.Get ready: These are just some of the products that could get more expensive if the United States moves forward with proposed tariffs on billion worth of Chinese products, and companies decide to pass the cost of the new taxes on to customers.On Tuesday, the Trump administration identified about 1,300 exports from China that could be targeted in the wake of a months-long investigation into intellectual property theft. The lengthy list includes a wide range of items, from airplane parts to syringes.The 25% tariff, which would be applied to all products, won't go into effect immediately. And the list isn't final. There's still time for businesses to lobby the government to remove certain items, and additional products can still be tacked on.But the current list would almost certainly lead to higher price tags on consumer electronics and various home appliances — including flat-screen TVs and home dishwashers."There's potential this a major hit to the pocketbooks of Americans, based on what we're seeing right now," said Jack Cutts, senior director of business research at the Consumer Technology Association.The USTR is also weighing tariffs on a number of key components in electronic devices, such as LED lights, copper wire, and capacitors and resistors. It's possible that companies will ask consumers to pay more to make up for higher costs in the supply chain."We're down at the basic building blocks of consumer electronics," Cutts said. These parts are included in items from computers to printers to smart refrigerators and coffeemakers, he said.The USTR list contains a lot of other inputs in final products, like screws, pulleys and motor parts.Whether prices rise will ultimately depend on the availability of substitutes, said Brad Setser, senior fellow for international economics at the Council on Foreign Relations.And companies might find ways to skirt the tariffs by making greater use of manufacturing facilities in other countries, like Brazil and Vietnam."Simply because it costs Apple that much more doesn't mean the consumer will pay [that much] more," said Awi Federgruen, a Columbia Business School professor who studies supply chain management.There's no easy way to determine if companies will decide to raise prices — and if so, by how much.Still, higher prices of any kind could make things tough on stores and shoppers — especially during the upcoming holiday season."These tariffs might be Grinch tariffs," said David French, senior vice president of government relations at the National Retail Federation. He noted that retailers will make decisions about where to source what they sell in December in coming weeks.Right now, companies are combing through their supply chains to see whether they might be impacted.The USTR list included a lot of general manufacturing equipment, so there could be additional revelations about affected products in the days and weeks to come.For example, even though clothing, shoes and toys were excluded from the initial list, parts and machinery used to manufacture these items may have been included, which could affect pricing.There are also lingering concerns that such items may find their way into the final draft."Items like apparel and footwear that are not on the list today, may suddenly materialize or appear on a later list," French said. 3388
