"However, on the prior groundless detention of Chinese citizen Meng Wanzhou by Canada at the behest of the United States, these same people made utterly different comments".
In the op-ed, Lu questioned whether countries such as the USA and Britain are truly representative of the worldwide community and he reiterated his government's assertion that Western countries are employing a "double standard" in judging his country.
"The reason why some people are used to arrogantly adopting double standards is due to Western egotism and white supremacy", he added. "What they have been doing is not showing respect for the rule of law, but mocking and trampling the rule of law", Lu wrote.
Lu Shaye was responding to Canada's demands for the immediate release of two Canadians, former diplomat Michael Kovrig and entrepreneur Michael Spavor, who were detained in China last month on vague claims that they threaten Chinese national security.
The U.S. reportedly said Meng deceived worldwide banks to funnel transactions between Huawei and Iran.
Meng has had a bail hearing in open court and has been released on conditions, while neither Kovrig nor Spavor has been formally charged or had access to lawyers.
"A shocking new low in Chinese diplomacy, and if Beijing doesn't recall Lu then Canada should consider PNG-ing him", Christopher Sands, director of the Johns Hopkins University Center for Canadian Studies in Washington, wrote Thursday on Twitter in an apparent reference to the term persona non grata.
Lu also wrote that Meng was arrested without violating any Canadian law, suggesting that Canada should never detain someone for extradition.
Canadian Prime Minister Justin Trudeau and US President Donald Trump in a telephone call on Monday, January 8, denounced the "arbitrary" detentions of Kovrig and Spavor.
"I don't know what the ambassador was trying to accomplish but his article won't help China's cause", Paris said. In the meanwhile, Canadians are getting edgy about traveling to China for fear of being randomly detained by Chinese authorities.
"He's making it seem like the two legal proceedings are morally equivalent and they are not", he said. "He says: 'You are being racist by not respecting our law.' That's an easy card to play".
"I have recently heard a word repeatedly pronounced by some Canadians: bullying. To those people, China's self-defence is an offense to Canada".
The detentions are widely viewed as Beijing's retaliation against the arrest and detention of Meng, who is the daughter of Huawei's founder as well as its current Chief Financial Officer.
But, in his column, Lu dismissed such concerns and instead pointed to monitoring and spying programs carried out by the US National Security Agency and the Five Eyes alliance countries (Australia, Canada, New Zealand, the United Kingdom and the US). "What's the logic?" he wrote.
US Secretary of State Mike Pompeo also called on China to end the "unlawful detention" of the two Canadians in a joint press conference with his Canadian counterpart Chrystia Freeland last month.
