China’s ambassador to Britain Zheng Zeguan was banned from the parliamentary estate last year – a move which sparked retaliatory sanctions on nine Britons, including senior Conservative MPs.
In an interview with the South China Morning Post, Mr Johnson Snr described Mr Zheng as a “very agreeable, capable and intelligent man” following talks with him about his travel plans for television.
The 81-year-old added: “I would very much hope that by the time parliament returns [after the summer break], these bans will no longer be in place.”
Mr Johnson’s government has accused Beijing of “egregious” abuses against the minority group, and slapped sanctions on Chinese officials deemed responsible for alleged human rights violations in Xinjiang.
The prime minister’s dad said his Xinjiang trip, funded by the English Path language school, would see him follow Marco Polo’s steps along the Silk Road – and will allow state broadcaster China Central Television to film his journey.
Asked whether he would raise any human rights concerns see along the way, Johnson Snr said: “We will be travelling with [our] eyes open and our ears open.”
He added: “You can be absolutely sure that … the TV team who are with us are absolutely professional – they will film what we see. I think that’s all we can say.”
He said his trip was “not a political exercise”, but also added: “Anyone who doesn’t want to improve British-Chinese relationships strikes me as being rather narrow-minded”.
Last month the PM’s dad was told his application to become a French citizen had been approved – calling it a “very nice gesture” of Paris authorities.
No 10 would not comment on Mr Johnson Snr’s trip to China or his call for the ambassador’s ban to be lifted.
Labour MP Catherine West, shadow minister for Asia, said Mr Johnson Snr’s comments were “particularly questionable when British MPs have been sanctioned by the Chinese government for speaking up for human rights”.
Announcing the ban on Mr Zheng last September, Commons Speaker Sir Lindsay Hoyle said it would not be “appropriate” to let the Chinese envoy on to the estate while MPs were subject to sanctions.
Beijing had earlier imposed sanctions on five MPs and two peers, including former Tory leader Iain Duncan Smith, over their stance on Xinjiang and China’s human rights record.
