While most of the attention in China this month was on the 19th Party Congress, we saw some surprising developments and discoveries that continue to challenge preconceptions about China.

The country's first seawater rice fields in Qingdao, Shandong province, have been harvested, with much higher yields than expected. This development could change the agricultural landscape and address concerns about food security.

The quality of researchers around the world will affect the race, but China may take the lead because of more data and differing norms on data collection and use. What’s surprising is how ubiquitous AI is becoming and where it turns up. Western audiences are familiar with Snapchat and Instagram, but how about Toutiao? The average user spends more than 74 minutes each day in Toutiao — more than twice what the average user spends on Snapchat.

Blockchain isn’t just useful in FinTech, Chinese companies are experimenting with distributed ledger technology to increase traceability of products like food, and fight the sale of counterfeit goods.

Self-service checkouts are proliferating around the world, but China is taking it one step further. It is testing out a new convenience store that relies on AI instead of managers to run the show.

We shouldn’t fear robots: they can assist doctors in treating patients, as Harbin Children’s Hospital is discovering with its treatment for children with autism. Doctors say the robots will perform an important role in encouraging children to speak.

Having piloted 10 parks across the country in 2016, the authorities have devised a scheme to put more of China's areas of outstanding natural beauty under protection. The tensions between preserving nature and economic development will not be solved overnight, however, and some of the most fragile ecosystems remain under pressure.

The world’s largest auto market has unveiled a comprehensive set of emission rules and delayed a programme related to the production of electric cars, giving automakers more time to prepare for the phasing out of fossil-fuelled vehicles.

These high-altitude unmanned vehicles are tasked with military intelligence gathering; they can fit inside a shoebox and cost just a few hundred yuan.

Sophia, a Hong Kong robot, was the first to be granted citizenship of a country, in a move that raises all sorts of questions. Controversially, her citizenship was granted by the kingdom of Saudi Arabia, sparking an outcry against a country that has been accused of making women second-class citizens.
