YANJI, China, Nov. 19, 2016 /PRNewswire/ -- Yanji has become one of the most popular cities attracting investments in Northeast Asia region. This success was made through the continuous efforts in developing the service sector, optimizing industrial structures and accelerating the pace of opening-up. Meanwhile, it explored a better way for small and medium sized cities to develop. A report published lately by Chinese Academy of Social Sciences indicated that Yanji has become the only city in Northeast China that is honoured both "National Top 100 Cities/Counties with Investment Potentiality" and "National Top 100 Cities/Counties with Comprehensive Competitiveness in Economy".
