COMMENT | Keeping international borders closed is pointless

COMMENT | International borders remain mostly closed in Malaysia despite vaccination rates surpassing 90 percent of its adult population.

Yet the same stringency has not been applied to domestic mobility restrictions, which have been trending downwards and culminating with the opening of state borders on Oct 11.

The announcement on the easing of interstate travel by Prime Minister Ismail Sabri Yaakob also noted that overseas travel by Malaysians would be allowed but subject to a 14-day quarantine on return.

This appears inconsistent since the same requirement is not being applied to interstate travel in a country that has had one of the world’s highest infection rates on a population-adjusted basis.

If it is safe to open internal borders despite an ongoing community outbreak, it should be safe to do the same with external borders, at least for returning Malaysians or tourists from countries with high vaccination and low infection rates.

Finance Minister Zafrul Abdul Aziz has indicated that Malaysia might open international borders by year-end to support growth. But why wait until then?

As Delta has become dominant in Malaysia and elsewhere, it has called into question many things, including the usefulness of the current combination of mobility restrictions at and within borders.

The variant’s high transmissibility has eroded the health-protective effects of border closures relative to domestic mobility restrictions, while the economic cost of border closures accelerates.

So far, most of the actions to support the economy in Malaysia and Southeast Asia have focused on easing domestic restrictions. Border restrictions have hardly featured in the calculus.

Because borders must remain mostly closed, the economic imperative has required so much domestic easing that health risks have risen sharply, as evidenced by soaring infection rates in Malaysia and Southeast Asia.

If this lopsided approach was suboptimal before, it is becoming unsustainable with the Delta outbreak.

Border measures carry a premium only while they keep new variants out. Once they fail, as they inevitably have, their value diminishes rapidly.

They fail for two reasons. First, borders are never completely closed, by design, because it would be both impractical and unsustainable to do so.

Domestic safeguards

Even the most vigilant countries, like Australia and New Zealand, have chosen not to close borders despite having the advantage of geographic isolation.

Second, because borders are not completely shut, domestic safeguards need to be close to perfect but they are not.

Domestic protocols can slip, as they have in Australia and New Zealand, leading to breakthrough infections during quarantine.

Travel bans are an attempt at completely closing the border to select countries and have been employed, unsuccessfully, with the emergence of each new variant.

By the time they are instituted against countries where the new variant has been spreading, it is simply too late to stop them.

Travel bans could work if we could reduce the time taken to determine the risks carried by the new variants, say, from the genetic sequencing alone, but this is not yet possible. Until it is, border measures will not protect us from future variants but improved domestic protocols might.

Therefore, keeping borders closed in the hope that it will protect us from the next variant is futile.

Shifting the focus

Now that the Delta variant has taken off in Southeast Asia, imported cases make up just a small fraction of total infections.

It is small not because border measures are working but because they did not, and therefore failed to keep out a highly transmissible variant that then spread rapidly domestically. Once this happens, the value of border measures relative to domestic restrictions falls sharply.

This suggests that shifting the focus from border to domestic restrictions, for any given health-economy trade-off, would be beneficial.

Such a shift would better address economic considerations while providing the best opportunity to contain community spread.

The recalibration should not go too far in restricting domestic mobility or it will deter foreign arrivals.

Now that interstate movement has been allowed, the opening of international borders is likely to be more successful in attracting foreign tourists.

Most countries in Europe and North America have also struck this balance and removed quarantine but have not carried out tests on vaccinated travellers from countries with low infection rates.

With sufficient healthcare capacity, it is time for Malaysia to do the same.

The only countries in Southeast Asia that have started opening their borders to non-essential international travel are Singapore and Thailand.

Singapore has opened up to more than 10 countries with low infection and high vaccination rates, most of which have reciprocated.

The single most important border policy change that Malaysia and Singapore can do to support economic recovery without risking health is to open up to each other.

Thailand has employed the sandbox or ‘micro herd immunity’ approach in the resort islands of Phuket and Koh Samui, opening up unilaterally to a large number of countries.

There have been no community outbreaks linked to international arrivals, although Phuket had to ban domestic arrivals after a surge in domestically imported cases.

The experience from Phuket’s opening highlights the relative risks of domestic versus international travel. It should not be surprising that it is domestic tourism that has been riskier in a country still battling a local outbreak.

There are lessons here for Malaysia, which has opened Langkawi to domestic but not international tourists.

Mutual recognition of vaccination certificates and other administrative protocols to open borders unilaterally or with reciprocity can be done expeditiously.

Now that vaccination rates have reached 90 percent, there is no value in waiting to open borders but only costs.
