At the London, Olympics, another country sees red over their flag.

Taiwan today expressed anger after Olympics organisers said the island's national flag had been taken down from a London display at the request of the Chinese embassy.

The flag was removed from a row hanging over Regent Street, one of London's busiest shopping areas, and replaced on Wednesday with that of Taiwan's Olympic committee.

Titles and flags are sensitive issues between Taiwan and China, as Beijing still claims the self-ruled island as part of its territory despite their split in 1949 after a civil war. Taiwan cannot display its national flag at international sporting events and other events as most countries formally recognise Beijing over Taipei.
