The past week was extremely hectic in Brussels, with the city hosting the European summit, the sixth high-level economic and trade dialogue between Beijing and the EU, several discussions on how China and Europe can cooperate on mega projects, and in between, a host of China-related cultural events.

Protectionism has dominated the minds of those in EU institutions, no matter whether they are involved in trade talks with visiting Chinese Vice-Premier Ma Kai, or whether they are dealing with the UK's exit from the bloc.

For years, the EU has been the global champion of free trade, multilaterism and advocating global solutions. But it is now challenged by multiple existential crisis, EU policymakers have been trying to put out one fire to another, and thus they have started to look inward and are failing to give enough attention to the future.

Even those that are taking notice of the EU's long-term blueprint are doing so with alarm.

Data suggests that, by the middle of this century, the EU's aging population mean it will comprise around only 5 percent of the world's total. And the fact that its population is shrinking means its market is shrinking too.

To negate this demographic transformation, today's EU leaders, if they want stronger and more sustainable European integration, should not seek protectionism or isolation.

On the positive side, most of the discussions at China-related meetings and talks away from trade negotiations have been more encouraging.

When deputy Belgian Prime Minister Kris Peeters met Ma on Tuesday, he pledged that Belgium would abide by World Trade Organization agreement protocols. Also last week, Peeters said Belgium expects to become a member of the Asian Infrastructure Investment Bank next year and is determined to "gain" from the Belt and Road Initiative.

Such attitudes have already been expressed by other EU member states, including the UK, the Czech Republic, Greece and Hungary. Sadly, the EU as a whole, on many occasions, has not been capable of this.
