Both trips have been accompanied by events in Hong Kong looking at how to combat counterfeiting.
"For too long, these illegal activities have been perceived as 'business as usual.' But not any more," said US Attorney General Eric Holder.
Holder gave the keynote address at the 2010 International Law Enforcement IP Crime Conference, which was co-hosted by Interpol and Hong Kong Customs.
Holder stressed the need for greater international cooperation: "Let me be blunt: Not every country, not every organisation has done enough."
Holder said he was going to Beijing to discuss how the US can develop bilateral enforcement efforts in China through the IP Working Group of the US-China Joint Liaison Group for Law Enforcement Cooperation.
"Together, I hope we can work to identify the most pressing, and perilous, gaps in our enforcement mechanisms," he said.
During his Beijing visit, China's Public Security Minister Meng Jianzhu announced a six-month crackdown on counterfeiting.
"This special campaign will target all IPR infringements or violations no matter which industry or sector, be it hi-tech or audio and video products or food and other products," Meng is reported to have said.
Also this week, INTA has sent its annual delegation to China, which met officials from the State Administration for Industry and Commerce (SAIC), the Trademark Review and Adjudication Board, the China Trade Mark Office and SIPO.
"China is an important partner with INTA in the fight against counterfeiting," said Association president Heather Steinmeyer, giving the opening address at a two-day INTA Anti-counterfeiting Conference in Hong Kong.
At the last INTA Annual Meeting in Boston in May this year, INTA and the SAIC signed a Summary on Further Enhancing Cooperation between the two organisations.
During the opening address Bruce Longbottom, trade mark counsel at Eli Lilly and chair of INTA's Anti-counterfeiting Committee, said that the global economic slowdown had led to counterfeiters switching to making more everyday consumer goods and an increase in internet sales.
Candice Li, INTA's external relations manager for the same Committee, said that INTA was involved in the process of drawing up a draft EU criminal enforcement directive and, in the US, was giving comments on Senator Patrick Leahy's Bill that would enable the Department of Justice to shut down websites that sell fakes by taking away their domain names.
