Taking to Instagram on Sunday, Donatella Versace, head of the legendary Italian fashion house that her brother founded, said she was "deeply sorry", alluding to the Chinese social media firestorm that erupted over the weekend.
The hotel chain's statement read: "Marriott International respects and supports the sovereignty and territorial integrity of China...we don't support anyone who subverts the sovereignty and territorial integrity of China and we do not intend in any way to encourage or incite any such people or groups".
The luxury fashion label's chief creative officer Donatella Versace has since apologised for the offending garment, calling the mislabelling an "unfortunate [.] error".
Photos of the T-shirt were also circulating on social media.
The backlash comes as China steps up its response to months-long anti-Beijing protests in Hong Kong, which along with the gambling enclave of Macau is a special administrative region of China. "I love my motherland and I resolutely safeguard national sovereignty". The brand also added that actions have been taken to recall the "inaccurate T-shirt design" from all markets, and that "measures of product and process review have been and will continue to be taken to avoid similar situations in the future".
However, instead of printing Hong Kong and Macau as part of China, the shirt only showed Hong kong-Hong Kong and Macau-Macau. "National sovereignty and territorial integrity are sacred and can not be violated under any circumstances".
Similarly Coach's ambassador, Chinese model Liu Wen, said she was terminating her work with the brand over its T-shirt blunder.
The Milan-based luxury clothing manufacturer is the latest company to become entangled in political issues involving China, which since previous year has increased its policing of how foreign firms describe Hong Kong and Macau, former European colonies that are now part of China but run with a high degree of autonomy. "We recognize the severity of the situation and sincerely apologize".
Last year, USA fashion brand Gap also faced similar backlash following the printing of a shirt that showed an "incorrect" map of China.
Weibo, an app similar to Twitter, is China's largest social media platform. Other companies, such as Marriott and Delta Airlines, also faced criticism previous year over the way they treated China's sovereignty claims.
