Last week an investigation by Le Monde made shocking allegations that the AU headquarters - built in Addis Ababa, Ethiopia, by the Chinese government - were being spied on. It was alleged that the computers donated by China had been transmitting information to the Chinese server in Shanghai since 2012.
It was reported that the AU learnt about the alleged tapping last year and had since acquired its own computer servers.
On Sunday, Lin held a media briefing where he dismissed the allegations, calling them a malicious smear campaign.
“We are not surprised by this smear campaign. This is to harm our passion and sincerity to the African continent. We are not even angry because we expected this from them (the West),” he said.
Lin said he was also disappointed in local media who ran the story.
“For China it's not the story itself, but the fact that some of our African media friends have easily fallen into the trap and followed suit without seeking truth from fact, that is particularly hurting. African journalist friends, leverage your own unique strengths to tell real and vivid stories of China-Africa friendship,” he said.
Lin said certain countries wanted to keep Africa trapped in poverty, conflict and instability.
“They want to continue colonising, controlling and manipulating Africa. They don’t want to help Africa realise durable peace and self-sustainable development. Even worse, they don’t want China and other countries to help Africa,” he said.
Lin, who spoke on the billion dollar investments made by China in South Africa and the African continent, said people feared and were frustrated over Chinese investments and projects on the continent.
He said China was all for helping Africa gain infrastructure, resourcing and financial development.
On the continent, Lin said, more than 80 sports stadiums, 200 schools and 20 parliamentary buildings had been built by China.
The country had financed the building of more than 6 500km of railways, 6 000km of roads and more than 70 power plants.
"China never attaches any political strings, never makes others do things against their will, never interferes with others domestic affairs," Lin said.
"China has never had problems in exchanging information with African brothers and sisters, and therefore has absolutely no need to resort to such despicable and disgraceful moves.”
