China's Domestic Economic Belt

Less well known on the world stage than China's land and sea "One Belt, One Road" and "Maritime Silk Road" is China's Domestic Economic Belt along the Yangtze River from densely-populated and heavily-polluted Shanghai, west to the lake region around Wuhan (where COVID-19 originated), and still farther southwest to Chongqing, population over 30 million, larger than Shanghai and Beijing (home to OneSpace, China's solid-fueled commercial spacecraft industry, specializing in launching small satellites) and Chengdu, where police just raided an underground church about to commemorate the June, 1989 democracy demonstration in Tiananmen Square. (This is an opportunity for students to trace the Yangtze River on a map of China.)

Attention to ecology along this Yangtze River route is a priority in China. It entails:

  •  Closing polluting chemical plants
  •  Restoration of lakes and wetlands 
  • Sewage treatment 
  • Regulating the fishing industry
  • Developing clean air technology (See earlier post,"How to Meet the Clean Air Challenge.")
  • Integrating non-polluting energy sources into the existing power grid'
  • Building new eco-friendly communities (See earlier post, "Priority: Eliminate generating electricity from fossil fuels.")
A new project in China's far western reaches demonstrates Beijing's focus on developing non-polluting energy sources. Where the Yangtze is known as the Jinsha Jiang River, the new Lawa hydroelectric dam will generate two billion watts of power, the same energy supplied by the U.S. Hoover Dam, on the border between Sichuan and the Tibetan Plateau.
     Development along the Yangtze also indicates China's interest in technological progress.  Economic assistance is going to the Donghu New Technology Development Zone east of Wuhan. The zone houses the FiberHome Technology Group, an optic fiber communications center, and the Wuhan Xinxin Semiconductor Manufacturing Corporation. Producing memory chips for China's semiconductor industry has become a personal priority of President Xi Jinping.

The U.S. Commerce Department's April, 2018 7-year ban on sales of chips to ZTE, the high-tech firm in China's integrated circuit and Smartphone industry, exposed dependence on exports from Qualcomm in California. Once again the consequences of cheating played a part. False statements and missing export records showed ZTE violated a 2017 settlement by illegally using U.S. chips in telecommunications equipment shipped to Iran and North Korea. Although ZTE had settled the 2017 case by paying a $1.2 billion penalty and promising disciplinary actions against 39 employees involved in illegal conduct, ZTE took no personnel measures. To restore Qualcomm's sales to ZTE, the company agreed to install a new management team and to let the U.S. staff a compliance unit that would report to the U.S. Commerce Department for the next ten years. At first the US Congress still rejected the plan, until President Trump and Chinese President Xi reached a separate agreement. 

Violations of the original ZTE technology agreement and other cases of Chinese infringement on intellectual property rights concern the U.S. about China's interest in stealing chip research, development, and manufacturing know-how, not only how work in these areas is progressing at the zone in Donghu. With nearly 350,000 Chinese students in the United States, universities are warned to lock their labs, and legal interns from China are being kept away from sensitive antitrust cases. (See the post concerning Foxconn's intended facility in Wisconsin in the later post, "Unmask Inscrutable Chinese Intentions.")

How to Meet the Clean Air Challenge

Similar to the process of producing clean water, one method China uses to attempt to reduce chronic smog pollution moves dirty air through a filtration system.

     In Beijing, a Dutch invention cleans air using a 23-foot, cylindrical filtration tower powered by electricity from a coal-fired power plant. A 300-foot tower surrounded by coated greenhouses in Xian, Shaanxi province, is experimenting with a more complex process. In daylight hours, solar radiation heats polluted air in the greenhouses before it rises in the tower through a series of purifying filters and is released into a 3.86 square mile area. Thus far, the Xian tower, when treating severely polluted air, especially in winter when coal provides heat in the area, shows only a 15% reduction in the fine small particles most hazardous to health. Yet, Xian's developers have an ambitious plan to construct 1,640-foot anti-pollution towers, each surrounded by 11.6 square miles of greenhouses, in other Chinese cities.

     Based on the Australian study mentioned in the earlier post, "Priority: Eliminate generating electricity from fossil fuels," coal-fueled power plants are the major source of pollution. These air filtration towers would seem to do the most good, if they were located in the vicinity of power plants.

     Startups and traditional automakers throughout the world race to produce the electric cars that promise to eliminate a source of pollution, the fossil fuels that power today's cars and trucks. The challenge to up the percentage of electric passenger cars from less than 1% on the world's roads today to at least 33% by 2040 involves financing, designing, engineering, manufacturing, charging stations, searching for the lithium used in batteries, and marketing. China is the industry's acknowledged leader with Tesla in the U.S. and European automakers also in the hunt.

     Although China is expected to continue to import lithium from South America's Argentina-Chile-Bolivia Belt (See the earlier post, "Technology's Hard Sell and the Public's Role in the Lithium-ion Battery Industry."), it has its own domestic supply. In the cold, thin air high in China's mountains between the Tibet Autonomous Region and the Xinjiang Uighur Autonomous Region, mining in Chaerhan Salt Lake is on track to supply a plant that will produce 30,000 tons of lithium carbonate by 2020 or 2021 and eventually plants that produce 200,000 tons annually.

     China also has ideas for creating charging methods to keep electric cars on the road away from home. When driving long distances, drivers could visit automated swap stations to switch their dying batteries for new ones in three minutes, or they could call mobile vans to come and recharge their dying batteries in ten minutes. (I cannot help but recall the toxic nano particles a high school student found, when her summer intern project at the University of Wisconsin studied the effects of decomposing lithium batteries. See the earlier post, "The Challenge of New Technologies: Prepare to Think.") By requiring foreign auto dealers to sell only electric cars and to provide charging options, China is in a position to restrict entry into the world's biggest market.
