Zuckerberg,

wife on

Chinese TV

Social media sites and blogs have lit up after eagle-eyed viewers spotted a surprise cameo in a Chinese TV documentary about the country's police force: Facebook founder Mark Zuckerberg and his wife, Priscilla Chan.

The documentary was part of a series on Chinese police and high-tech crime-solving methods. A report on the CCTV show was posted online by the Hebei province satellite station that included a few seconds of Zuckerberg and Chan walking behind two police officers.

The footage shows the couple wearing the same clothes they were photographed in during a March 27 visit to Shanghai.

The clip shows Zuckerberg looking at the camera and smiling broadly before the couple walks off-screen. As they are shown, the narrator says: "There is a serious shortage in China's police manpower."

BUENOS AIRES, ARGENTINA

Rules on foreign

currency tightened

Argentina is making it harder for people to buy U.S. dollars to pay for travel abroad.

A new rule published Monday says anyone wanting to buy dollars for travel must first prove their money was obtained legally, and provide the tax agency with trip details including why, when and where they are traveling.

Many Argentines only declare part of their wealth and income to evade taxes, and use black-market currency exchanges to convert their inflationary pesos into dollars. Travel agencies are the latest target since they manage multiple currencies

and offer customers black-market rates for their money.

BlackBerry maker

loses another executive

Struggling BlackBerry-maker Research In Motion Ltd. said Monday that it is losing another senior executive as its chief legal officer is retiring from the company after 12 years.

RIM said that Karima Bawa had been in discussions about her retirement for some time and plans to stay on to help with the transition once a replacement has been hired.

The once-iconic BlackBerry company is facing its most difficult period in its history. RIM is working on launching a new software operating system just as North Americans are abandoning their BlackBerrys for Apple's iPhone and smart phones that run Google's Android software.
