Edmund Ho
In 2007, local residents of Macao wrote a letter to UNESCO complaining about construction projects around world heritage Guia Lighthouse (Focal height 108 meters), including the headquarter of the Liaison Office of the Central People's Government in the Macao Special Administrative Region (91 meters). UNESCO then issued a warning to the Macau government, which led former Chief Executive Edmund Ho to sign a notice regulating height restrictions on buildings around the site.
