Calling the United State's statement on the Tiananmen Square massacre last Friday as interfering in its "internal affairs," the Beijing government urged the U.S. government to stay away from its internal matters.

Spokesperson of the Chinese Foreign Ministry Hong Lei said that the U.S. releases "similar statements year after year, ignoring facts and making groundless accusations against the Chinese government," which the spokesperson said is a "rude interference in China's internal affairs."

The U.S. State Department last Friday had called upon the Chinese government to fully account for those killed, detained or missing in the 1989 military crackdown on the peaceful students-led demonstration in Tiananmen Square.

The State Department spokeswoman Jen Psaki stated that the U.S. was remembering the "tragic loss of innocent lives" ahead of the 24th anniversary of Tiananmen Square massacre which falls on June 4.

"We renew our call for China to protect the universal human rights of all its citizens; release those who have been wrongfully detained, prosecuted, incarcerated, forcibly disappeared, or placed under house arrest; and end the ongoing harassment of human rights activists and their families," said Jen Psaki in the statement.

In an open letter published by the New York-based Human Rights in China, the mothers of those killed in Tiananmen Square massacre criticized the new Chinese leadership of Xi Jinping for failing to make any political reforms in the country.

The activist group known as Tiananmen Mothers has released a bunch of open petition-letters over the years seeking justice for the victims of the 1989 demonstration in Tiananmen Square.  

"During these long 24 years, we Tiananmen Mothers have suffered profoundly. We have moaned in hell-like darkness, struggled in tears, which nearly dried up. We have also been overwhelmed by fear and despair and engulfed by rumors and apathy," the group said in the open letter.

"We have campaigned year after year, tried to get back justice for the dead year after year. The government authorities, however, have remained unmoved," said the group.

The historical demonstration has been almost washed away from the Chinese public memory and no trace of the demonstration remains except one or two sentences in the Chinese history text books as "counter-revolutionary riot."

Because of its dictatorial and repressive security measures and policies, China is unlikely to see any demonstration at the square during its 24th anniversary, which is tomorrow.

The topic of Tiananmen Square remains taboo in the country.
