China Datin Magdalene was appointed as Ambassador to China in 2007 and officially presented her credentials to President Hu Jintao in April 2008 and it was this appointment that defined her diplomatic legacy. Over the next decade, as Ambassador Extraordinary and Plenipotentiary, she became a central figure in shaping the modern Brunei–China relationship at a time of rapid geopolitical change.

During her tenure in China, Ambassador Teo participated extensively in diplomatic activities and cultural engagement. She attended cultural events, academic forums, provincial visits, and ASEAN-China activities. Chinese officials and academics described her diplomatic approach as characterized by consistent relationship-building and personal engagement.

Ambassador Teo was equally committed to education and cultural exchange, believing that the future of bilateral relations lay not only in government agreements but in the ties forged between students, artists, and ordinary people. In Guizhou in 2013, at an exhibition showcasing Bruneian photography, she spoke of culture as a “unique bridge of understanding,” capable of making peoples “closer and more friendly.” She also encouraged Chinese universities—particularly those outside the major coastal hubs—to develop lasting academic partnerships with Bruneian institutions.

A key highlight was a 2016 ceremony marking the 25th anniversary of Brunei Darussalam–China relations. Highlighting and celebrated the more than 40 mechanisms of cooperation that had grown between the two countries.

Behind the scenes, she supported Brunei’s economic engagement with China, including cooperation on industrial development, tourism, and connectivity. Her calm, culturally attuned diplomacy laid the soft-power foundation for large-scale collaboration that would later deepen under the Belt and Road Initiative.

In recognition of her contributions, she was awarded the Darjah Paduka Mahkota Brunei, Second Class (DPMB) in 2012, receiving the title Datin Paduka.

She returned to Brunei after completing her term in China in 2018.
