Singapore is committed to keeping the Strait of Malacca open, the city state’s top diplomat Vivian Balakrishnan has told his Chinese counterpart Wang Yi during talks in Beijing.

According to the Chinese government, the Singaporean foreign minister said on Monday that keeping the critical global shipping lane open was in the interest of all parties.

The matter arose last year amid speculation that US President Donald Trump’s administration could be eyeing shipping chokepoints around the world as a strategic priority, after top officials repeatedly spoke of wanting to “take back” the Panama Canal from alleged “Chinese influence”.

China relies on the Strait of Malacca for more than half of the oil and roughly 4 per cent of the natural gas it consumes each year.

Such dependence has long been seen as a strategic vulnerability.

Any disruption to the maritime artery, whether because of natural causes or human factors, could deal a serious blow to the world’s second-largest economy.
