The United States and China are acting tough over trade, but they're also busy talking to try to stop the situation spiraling out of control.President Donald Trump ramped up tensions last week by ordering tariffs on about billion worth of Chinese goods just weeks after announcing of sanctions on steel and aluminum imports. Beijing has responded with plans to target billion worth of US products and warnings that it's ready to inflict more pain.The moves have fueled fears that the situation could escalate into a full-blown trade war between the world's two largest economies. But Treasury Secretary Steven Mnuchin said Sunday that he's been talking to Chinese officials in an effort to prevent that."We're not afraid of a trade war, but that's not our objective," he said in an interview on Fox News."We are going to proceed with our tariffs ... we're also working on investment restrictions," Mnuchin said. "But we are simultaneously having negotiations with the Chinese to see if we can reach an agreement."The US government wants China to do a lot more to open up its vast economy to US businesses and bring down the massive trade deficit between the two countries.Trump has set a target of cutting the deficit in goods with China by 0 billion. It soared to 5 billion last year, according to US figures.Mnuchin said the United States wants China to do away with rules that require foreign companies to set up joint ventures with Chinese firms in many industries, such as automobiles, and to stop forcing American businesses to hand over valuable intellectual property in order to operate in China. Intellectual property theft is the reason the Trump administration gave for the planned billion in tariffs on Chinese goods.Mnuchin and US Trade Representative Robert Lighthizer detailed the US requests in a letter to a top Chinese economic official late last week, according to the Wall Street Journal. They included asking Beijing to reduce tariffs on American cars, increase spending on US semiconductors and provide greater access to the Chinese financial sector, the Journal reported, citing unidentified people with knowledge of the matter.A Treasury Department spokesperson declined to confirm the report."We are having very productive conversations with them," Mnuchin told Fox, adding that he was "cautiously hopeful" that the two sides could reach a deal. But in the absence of "an acceptable agreement that the president signs off on," the Trump administration will press ahead with the tariffs and other measures, he warned.China's point man for the talks is Liu He, a Harvard graduate who is one of President Xi Jinping's most trusted advisers. Liu was in Washington for talks with US officials the week that Trump announced plans for the tariffs on steel and aluminum and was recently appointed to the position of vice premier.Mnuchin and Liu spoke as recently as this weekend."Secretary Mnuchin called Liu He to congratulate him on the official announcement of his new role," the Treasury spokesperson said. "They also discussed the trade deficit between our two countries and committed to continuing the dialogue to find a mutually agreeable way to reduce it."China's official news agency Xinhua also reported the conversation, saying that Liu criticized the US allegations of Chinese intellectual property theft and warned Mnuchin that China "has the capability to safeguard its national interest."But Liu also said that China "hopes to see both sides remain sensible and work together to preserve the overall stability of China-US trade relations," according to the Xinhua report.Some experts are skeptical that Beijing will give Trump what he wants."China may be able to come up with some big ticket imports to allow it to appear to be trying to reduce the bilateral trade imbalance," Mark Williams, chief Asia economist at research firm Capital Economics, wrote in a note to clients on Friday. "But China won't be able to reduce the annual imbalance by 0bn as Mr Trump has demanded."And "the chances of China making substantive changes to its practices on intellectual property are also low," Williams said, adding that the practices are seen in Beijing as "a key element" of efforts to develop the Chinese economy.  4274

The suspect in the deadly terror attack in New York wasn't only a driver for Uber. He also worked for its rival Lyft.Lyft said late Wednesday that Sayfullo Saipov drove for its ride-hailing app in the past but that it deactivated his account as soon as he was identified as a suspect in the attack.Saipov, a 29-year-old from Uzbekistan who was living in New Jersey, has been charged with federal terrorism offenses in connection with Tuesday's attack in Manhattan in which eight people were killed.Uber said Tuesday that Saipov started driving for it in New Jersey just over six months ago, making more than 1,400 trips. It also banned him from its platform after the attack.Lyft didn't provide details on how long Saipov drove for its app or how many trips he made. It's not unusual for drivers to work for both companies.Saipov's case is drawing renewed attention to the background checks that ride-hailing companies carry out on their drivers.Records show Saipov received multiple traffic citations in the past, including failure to equip a motor vehicle carrier with or maintain a required brake system.Both Uber and Lyft said they hadn't come across any complaints about Saipov's safety as a driver for them.New Jersey rules for ride-hailing services like Uber and Lyft require the companies to conduct criminal background checks, which are usually outsourced to specialist firms. Convictions for crimes like reckless driving automatically disqualify a driver.Uber applies different criteria for background checks depending on state regulations. In general, drivers cannot have more than three minor moving violations, such as speeding tickets, in the past three years.Lyft's website says potential drivers are screened for "driving incidents" but doesn't specify what would disqualify them.Both Uber and Lyft say they are in contact with law enforcement authorities over the New York attack."Our thoughts are with those affected by this tragic act," Lyft said. 1999

The United States and North Korea have been holding secret, direct talks to prepare for a summit between President Donald Trump and North Korea leader Kim Jong Un, a sign that planning for the highly anticipated meeting is progressing, several administration officials familiar with the discussions tell CNN.Central Intelligence Agency Director Mike Pompeo and a team at the CIA have been working through intelligence back-channels to make preparations for the summit, the officials said. American and North Korean intelligence officials have spoken several times and have even met in a third country, with a focus on nailing down a location for the talks.Although the North Korean regime has not publicly declared its invitation by Kim Jong Un to meet with Trump, which was conveyed last month by a South Korean envoy, several officials say North Korea has since acknowledged Trump's acceptance, and Pyongyang has reaffirmed Kim is willing to discuss the denuclearization of the Korean peninsula. 1005

The spread of COVID-19 is tough to trace and even tougher to predict, but researchers at Pittsburgh’s Carnegie Mellon University created an early warning system to help protect you from the virusMathematics professor Po-Shen Loh developed an app called NOVID, a contact-tracing app, to help communities see the virus coming before they get infected.On top of creating a brand new app, Loh teaches math to middle-school students online from his own office-turned-broadcast studio. He’s also the national coach for the United States Math Olympiad team that competes around the world.But when the pandemic hit, Loh wanted to take on one more project. “I like things that are supposed to be impossible, that can’t be done,” said Loh. Stopping the spread of the coronavirus seemed to fit the bill.“The problem with COVID is it spreads before you know you have it, that’s what makes COVID different," Loh said. "The only way you can control this disease is in helping people to know whether or not COVID is coming close to them in advance."That’s where the NOVID app can help, said Loh. “Shows the virus coming towards you based on your relationship network, so that you can protect yourselves from others before you actually get infected," Loh explained of the app. "This is in contrast to most other contact tracing apps that are designed to protect others from you."The app shows you positive cases in degrees of separation. A positive case in the first degree would be someone you live with. The second degree could be your coworker or a friend. The third degree would be that person’s spouse or child. Each degree of separation is a possible pathway for you to come in contact with COVID-19.“This thing shows you the virus coming towards you, kind of like a hurricane satellite shows you a hurricane coming towards you,” said Loh.In addition to showing you cases as they pop up around you, the app can track the distance between phones down to the inch.It uses both Bluetooth and ultrasound waves to give you that measurement to make sure you’re safely social distancing.“We don’t know of any other contact-tracing app in the entire world which will tell you, ‘here’s how far away we think the device was,’” said Loh.The safety of your personal information is one of the most important features of this app. It collects data, while you stay completely anonymous.“Many people are distrustful of an app that does contact tracing,” said Loh. “We never ask for your phone number or email."Those who are positive can self-report their case in the app. Loh is also working with cities and counties to integrate NOVID into health departments across the country. He said the health departments would issue a ticket with a number to each person who tests positive for the virus.That person would enter the number into their NOVID app, anonymously reporting the positive case in the community.“If this thing actually caught on, you’d see in all the cities and towns, whether it’s rural or urban, whenever COVID starts to rise up, you’d start to see everyone take caution. Not because anyone forced them to, but because they saw this is what would be useful,” said Loh.To create the powerful community resource Loh is hoping for, he said more people need to know about the app.“Right now, we only respond when the intensive care units are full, and then it’s too late, and people die on the sidewalk. But, what we wish would happen, is that people could see it coming, and then, everyone starts to be careful at the right time. With more traction, we can save more lives,” he said.Loh is hoping he can not only help save lives but help bring back life as we knew it.“The goal of what we’re trying to do is to give people headlights to drive in the dark. Our app is not designed to let other people control you; our app is designed to help you control your life,” said Loh.For more information on NOVID or to download it, click HERE. 3928
