President Xi Jinping's administration's use of military retaliation is "a worrying escalation" and could result in further pressure on future business dealings, said Hugo Brennan, Asia analyst at Verisk Maplecroft, in a Wednesday note.
Companies that have interests or operations in blocks licensed by Southeast Asian governments but located within China-claimed waters are likely to face pressure from Beijing, according to Brennan.
There are many overlapping claims in the region. China relies on a concept known as the nine-dash line to mark its territorial claims — a massive area that extends roughly 1,000 miles from its southern shores — in the South China Sea. But Vietnam, the Philippines, Malaysia, Brunei and Taiwan also assert sovereign rights over parts of the international waterway, which is rich in resources and boasts key maritime routes.
Against that backdrop, firms licensed by other countries to operate in disputed ares will face Chinese protestations. Any company ignoring those would likely face consequences such as on-site harassment, de facto exclusion from the Chinese market and even implicit threats to company staff and assets, Brennan said. BP experienced the latter option in 2007, he added.
"Operators also have to analyse the resolve of Southeast Asian governments to stand up to China. Otherwise, companies with rights to develop blocks or fields in contested waters may find that they are prevented from exercising them as host government become wary of rocking the boat."
The next potential flash-point could be Vietnam's Red Emperor oil and gas field, also called Ca Rong Do. Repsol is active in the project, which is located within China's nine-dash line, and drilling is slated for 2019. But in light of Chinese threats, it remains to be seen how much progress the Madrid-based firm will make, Brennan said.
