BEIJING (AP) – The Olympic torch touched down in Beijing on Monday amid high security before it leaves on a round-the-world relay expected to be a lightning rod for protests against China’s policies and human rights practices.The lighting ceremony a week ago in Greece was marred by protests, and a pro-Tibetan group demonstrated again Sunday when Greek officials handed over the Olympic flame to organizers of the Beijing Games in Athens.The torch arrived in Beijing aboard a chartered Chinese plane, allowing the government a brief respite before the relay sets off on a problematic, monthlong world tour.Authorities have given few details about a torch welcoming ceremony later Monday in Tiananmen Square, the heart of China’s capital.After a one-day stop in Beijing, the flame goes Tuesday to Almaty, Kazakhstan, the start of the 20-country, 85,100-mile global journey.The grandiose relay is the longest in Olympic history and has the most torchbearers – a sign of the vast attention lavished on the Games by Beijing, which hopes to use it to showcase China’s rising economic and political power.Instead, however, it has provided a stage for human rights activists who have been criticizing China over a range of issues including its control over Tibet, its relationship with Sudan and its handling of Muslims in the far west of the country.
