The European Union and China will sign a deal on Wednesday that will protect regional foods against counterfeiters. The accord will mean that one hundred Chinese and EU products will have a geographical indication on the packaging that will prove their origin.

The list of products from China that will now be protected includes 28 teas, 14 different fruits, seven kinds of mushrooms, three types of coffees, and four types of rice.

French President Emmanuel Macron announced the agreement on 4 November after arriving in China to visit Shanghai's financial hub and to attend a gala dinner hosted by China's president Xi Jinping. Macron is visiting China with EU trade commissioner Phil Hogan, who will go to Beijing on 6 November to sign the geographical indication accord.

Duck city

After the deal is signed a type of duck, Nanjing Yan Shui Ya (Nanjing Salted Duck), will be labeled so that consumers will know that the dish is authentic. 

In Nanjing, the capital of Jiangsu Province, ducks are so popular that there are several sayings that express Nanjing's love for the meat. One is that "there is no duck that can walk out of Nanjing alive," another is "no duck, no feast.”

Every day, Nanjing residents eat 80,000 ducks, which totals more than 29 million every year. 

The dish - which is marinated, dry-aged, boiled for 20 minutes and then drained and boiled again -  was created 2,500 years ago. 

The world's most expensive tea

Da Hong Pao, a tea from Fujian Province, is one of the most expensive teas in the world. In 2016, a Chinese restaurant in London, the Royal China Club, served a pot of this tea for £180 ($232).

At the time, it was the most expensive tea in London, and was featured in a Buzzfeed series called "Worth It" in which people try products at three price points. The restaurant is no longer serving this tea. 

Moutai, one of the world's most famous liquors

This luxury drink is made in Central China and is considered China's "national liquor." It is usually served at state banquets. The company that makes the liquor, Kweichow Moutai, is based in a city that shares its name, Maotai town in Guizhou Province.

This year, Kweichow Moutai's revenue was $5.5 billion. It is the most profitable company in China, outside of the technology and finance sectors, according to the Financial Times. 

The drink is expensive, and the price of the drink can vary from $209 to $5,999.
