Prime Minister John Key's says he is unhappy he had to disrupt his programme in Shanghai to address the issues of the GCSB report.
He goes to Beijing about 2pm today for an official welcome at the Great Hall of the People by Premier Li Keqiang and a new round of talks.
Mr Key had talks on Sunday with President Xi Jinping on Hainan Island.
"About the last thing we wanted to be doing is standing here in China dealing with this," he said at a press conference convened in his hotel after the Government decided to release the report early because of leaks.
Mr Key had to give up only one appointment - a visit to a Shanghai supermarket to promote New Zealand produce - which Trade Minister Tim Groser did instead.
