The operators of the world's only museum chronicling the Chinese government's brutal 1989 crackdown on student protesters in Beijing's Tiananmen Square say it faces closure because of a legal dispute.

The pro-democracy group behind the tiny Hong Kong museum said Friday that they have decided to look for another space rather than fight a costly lawsuit launched by other owners of the building where the museum is located.

The June 4th Museum, which opened two years ago, is dedicated to preserving the memory of one of the darkest chapters of modern Chinese history through photos, videos, artifacts and written histories.

The 75 square meter (800 square foot) museum is found in a small office building in the specially administered Chinese region's Kowloon peninsula not far from a major tourist district.
