The first Guangzhou Tirennial is a good check of the stew of styles emerging from Chinese art in recent years. It’s been a period of experimentation, and the rest of the world is taking notice. “As evidence of the growing global buzz about China’s art, opening night drew groups of collectors and donors from the Museum of Modern Art and the Asia Society in New York. And in a sign that its museums are also entering the global mainstream, the gift shop at the Guangdong Museum was filled with attractive tie-in products, including T-shirts and watches with images by leading artists.”
