Pakistani Prime Minister Imran Khan will lay the foundation stone Wednesday for what is dubbed as a cross-border "corridor of peace" to allow religious devotees from India's minority Sikh community to make free visits to one of their holiest gurdwaras, or temples, on the Pakistani side after more than seven decades.
The temple, known as Gurdwara Darbar Sahib, is considered to be the first temple ever built and the final resting place of Guru Nanak, the Sikhism founder.
Indian leaders, on behalf of the Sikh community, have long been demanding Islamabad provide unrestricted access to the holy site in Kartarpur, in Pakistan's Punjab province.
India's and Pakistan's independence from Britain in 1947 divided the Punjab province, where Sikhism was born.
Indian Vice President Venkaiah Naidu performed the groundbreaking Monday on his side of the corridor at a ceremony just two kilometers from the Pakistani border.
The mutually agreed-to project is rare between the two nuclear-armed South Asian rivals. Historically strained ties have deteriorated in recent years and bilateral official talks remain suspended.
The fenced corridor of about five kilometers aims to connect the Kartarpur temple to the Sikh holy shrine at Dara Baba Nanak in India's Gurdaspur district. Officials say the corridor will be in place for the 550th anniversary of Guru Nanak's birth in November 2019.
Khan's government has invited, among others, Indian officials and journalists for Wednesday's groundbreaking in Kartarpur, three kilometers from the border with India. An Indian ministerial-level delegation is expected to attend the ceremony as special envoys of Prime Minister Narendra Modi.
"Pakistan calls this a corridor of peace. I call it the corridor of infinite possibilities of peace," Indian Punjab provincial minister Navjot Singh Sidhu told reporters shortly after arriving in Pakistan for the ceremony. He crossed the border by foot at the Wagah crossing near the eastern Pakistan city of Lahore to attend the event at the invitation of his friend, Prime Minister Khan.
Members of the Sikh community on both sides have welcomed the construction of the cross-border corridor linking the two holy sites.
Indian pilgrims currently must seek visas to enter Pakistan and travel more than 200 kilometers to visit the Kartarpur shrine. The temple is visible on clear days from a viewing stage on the Indian side, where religious devotees gather every day to have a glimpse of it.
India and Pakistan have fought three wars, and mutual tensions often hamper pilgrims' plans to get timely visas to visit the shrine. Two of those wars have been over the disputed Kashmir region, which remains at the center of tensions.
