I was interested today to note this article in The Guardian, Seeing double: what China's copycat culture means for architecture. There are photos of remarkable unauthorised copies in China of famous monuments abroad, the copyright or reputations in which are associated with famous names in architecture such as Zaha Hadid and Le Corbusier.
The Guardian's theme is that copies are made of famous non-Chinese buildings and monuments, both old and new.
The one experience I've had with architecture, copyright and China runs opposite to The Guardian story.
A close friend is a distinguished architect. One of his greatest jobs was an inspired yacht club design and associated apartment development some years ago in Australia. Within a year of being finished, via an online search it caught the eye of people in south China who sought to establish a similar coastal facility.
