The first border trade zone between China and North Korea was established last Saturday morning in Dandong Moins Cher Femme Nike Air Presto QS Lac Bleu Blanche , Northeast China's Liaoning Province, media reported Monday.
The Guomenwan trade zone, with a total investment of 1 billion yuan ($156 million), and covering a floor area of 24,000 square meters, is scheduled to operate in October, the Xinhua News Agency reported on Tuesday.
Residents living within 20 kilometers of the border can exchange commodities with people from North Korea at the marketplace. Each resident can enjoy duty-free prices for commodities valued less than 8 Rabais Homme Nike Air Presto QS Bleu ,000 yuan per day.
The business model will be a combination of real economy and E-commerce, as products listed online will be showcased in physical shops and an E-commerce platform will be built to serve customers in different regions.
"Clothes might be a popular choice in the market, as the design process and delivery could be accomplished very fast with E-commerce," Li Guohua, an expert on Asia-Pacific studies at the Chinese Academy of Social Sciences told the Global Times, adding that China-produced phones and televisions are also popular items.

BUDAPEST, July 25 (Xinhua) -- Olympic champion Sun Yang of China won his first title in men's 200m freestyle at the 17th FINA World Championships here on Tuesday.
Placed sixth after the first 100 meters, Sun made a stong comeback to clock 1 minute and 44.39 seconds to record his groundbreaking victory, beating the Asian record of 1:44.47 he set in 2013. It was also his second title in the Hungarian capital after the 400m free.
"I feel happy about the gold medal. Actually I didn't expect such a result, and just wanted to work on every detail Homme Nike Air Presto Noir Achetez ," said Sun after his victory.
Sun claimed the golds in the 400m, 800m and 1500m freestyle before his 200m triumph at worlds. He is also the Olympic champion in 200m, 400m and 1500m freestyle.
"I lost the race with a bit pity at World Championships in Kazan two years ago. Today my dream has come true," Sun pointed out.
Townley Haas of the United States and Aleksandr Krasnykh of Russia finished second and third respectively.

SAN FRANCISCO, May 9 (Xinhua) -- A new technique has helped researchers take snapshots of molecules in chemical reactions and begin to build a toolbox that will help design or improve catalytic reactions.
The team of researchers at University of California, Berkeley, and Lawrence Berkeley National Laboratory has used non-contact atomic force microscope Homme Nike Air Presto Essential Noir Grise Pas Cher , or nc-AFM, to capture the fleeting molecular structures that reacting chemicals form on their way to a final product.
In a paper put online this week in advance of publication in the journal Nature Chemistry, the researchers reported that they had taken snapshots of two molecules reacting on the surface of a catalyst, and found intermediate structures lasting for the 20 minutes or so it takes to snap a photo.
Chemical reactions often take place within picoseconds, or a trillionth of a second, a process so rapid that chemists expect intermediate steps in the reaction to be too brief to observe. Only lasers firing in femtosecond bursts can capture the fleeting molecular structures that reacting chemicals form on their way to a final product.
""Intuitively, we did not expect to see these transient intermediates Nike Air Presto BR Noir Pas Cher , because they are so short lived,"" said Felix Fischer, an assistant professor of chemistry at UC Berkeley. ""Based on our traditional understanding, you would expect to see the starting materials and very shortly after, only the product. But we see these intermediates, so something else is going on.""
The explanation for these intermediates, or ghostly molecules Homme NikeLab Acronym Presto Mid Utility Noir Blanche Rabais , is now fleshing out details of catalytic reactions that chemists have only vaguely understood until now, and providing new rules for chemical reactions that chemists can exploit to make reactions go faster or more efficiently, or build molecules never before seen.
Fischer is beginning to build a toolbox that will help design or improve catalytic reactions, which are the workhorse of the world's chemical industry, responsible for producing everything from fuel to the building blocks of plastics, according to a news release from UC Berkeley on Monday.
The tools could also impact fields such as materials science, nanotechnology Nike Air Presto Homme Noir Rouge Pas Cher , biology and medicine.
In the past, chemists could only infer how chemicals change during the process, as bonds between atoms break and reform, branches rotate or join to form rings, and three-dimensional structures shift.
Three years ago, Fischer and UC Berkeley's Michael Crommie, a professor of physics Homme Nike Air Presto ISLAND Bleu Pas Cher , teamed up to apply atomic force microscopy to take snapshots of molecules before and after a reaction, trying to confirm what chemists have always inferred.
The nc-AFM hovers above a surface and detects individual atoms via a microscopic vibrating probe with a sensitive carbon monoxide molecule at its tip.
Fischer, Crommie and their colleagues place molecules on a gold or silver surface and heat them to make them react slowly, then use the nc-AFM to take snapshots over the course of the reaction.
During their first attempt to image a reaction between two molecules, they saw not only the starting chemicals and end product, but also two intermediate chemical structures that should not have been there.
