The new concept is the result of collaboration between Nissan Design China and the Nissan Global Design Centre.
Nissan's product boss, Andy Palmer, said: "It joins our growing family of China-focused models."
Its distinctive modern looks are hoped to appeal to younger buyers, the number of which is rapidly growing in China.
Taiji Toyota, head of Nissan Design China, says the Lannia Concept exudes “daqi” – a term that suggests upmarket aspirations.
The Chinese name of the concept, "lan niao yin xiang", is stated to pay tribute to the well-recognised Nissan Bluebird; it reputedly translates as "Bluebird impression".
