Zhao's specialized areas: space law, dispute resolution, international economic law, e-commerce law. In the past few years, Mr. Zhao has conducted different research in the area of space exploration. He is also currently exploring significant topics such as the problem of space debris, the exploration of the space resources, the non-appropriation principle in space, etc. Zhao is convinced that Hong Kong needs to update its 23-year-old outer space law to keep pace with the growing use of commercial satellites both in the city and overseas. Hong Kong introduced the Outer Space Act 1986 in 1990 and the Outer Space Ordinance in 1997. A lawyer noted that the Outer Space Ordinance has many grey areas. These included the copyright of raw data transmitted by satellites as well as the liabilities of different parties in the case of a collision in space.
