The handshake between the two leaders marked the latest milestone in a rapid rapprochement after months of global fears about nuclear conflict.

Here are some other handshakes that shook the world:

Obama-Castro, 2013 

At a memorial service for Nelson Mandela in 2013, US President Barack Obama made headlines when he shook hands with Cuba’s Raul Castro, the first such public greeting between leaders of the bitter neighbours after decades of enmity.

Within months, there was a rapid thaw. Full diplomatic relations were restored in July 2015, followed by once-unthinkable steps to mend ties after more than half a century of enmity.

Obama visited Cuba in 2016 — the first such trip by an American president in 88 years. Washington also relaxed its decades-long embargo on the communist-ruled island, and US airlines resumed direct flights to Havana in November 2016.

Queen Elizabeth-McGuinness, 2012 

In a landmark moment in the Northern Ireland peace process, Britain’s Queen Elizabeth II met Martin McGuinness, a former top commander in the paramilitary Irish Republican Army during the many years of bloody hostilities with British forces.

The IRA wanted an end to British rule in the province, and for it to be merged with the Republic of Ireland.

McGuinness later became one of the figures that helped negotiate an end to the violence.

McGuinness — then a deputy first minister of Northern Ireland — shook hands with the Queen during her 2012 visit to the province.

It was a gesture towards reconciliation that would once have been unimaginable, with McGuinness’ militant past and British security operations still a source of anger for many.

Xi-Ma, 2015

After decades of estrangement following a traumatic split at the end of a civil war in 1949, the presidents of China and Taiwan met for the first time ever in Singapore.

In unprecedented scenes, China’s Xi Jinping and Taiwan’s Ma Ying-jeou shook hands for more than a minute and smiled for a mass of reporters before holding talks.

The summit led to the setting up of a hotline between Beijing and Taipei and a lowering of tensions between the self-ruled island and the mainland.

While the meeting was undeniably historic, there were no major concessions from either side.

Ma ended up paying a heavy political price at home: Taiwanese voters chose to back Beijing-sceptic Tsai Ing-wen in the 2016 election amid fears about the island’s sovereignty.

Donald-Kim

The next major handshake on the global calendar is expected to feature Kim Jong Un again — this time with US President Donald Trump.

While it will certainly mark a historic moment, handshakes involving Trump sometimes make headlines for the wrong reasons, and the businessman-president has become well-known for his awkward grapples.
