This is going to be an eventful year for international politics. Aside from the sluggish global economic growth, major economies also have a lot to deal with at home. The controversial US Republican presidential candidate Donald Trump is one step closer to winning his party's nomination race, adding more uncertainties to the country's presidential election. Tensions still run high in the Middle East, while Russia is yet to reconcile with the West over the Syrian and Ukrainian crises.

The process of denuclearizing the Korean Peninsula, too, has hit speed bumps after the Democratic People's Republic of Korea conducted its fourth nuclear test on Jan 6 and launched an Earth-observation satellite on Feb 7.

More importantly, for major global powers, whether they are able to mobilize enough international support to fight cross-border terrorism led by the Islamic State, will serve as a barometer of their capability to fruitfully handle their relationships.

Defined as modern countries that have systematic impact on the international systems, major powers including the United States and China, are obliged to shoulder greater responsibilities and play a more active role in regional and global affairs. And to safeguard global peace, stability and prosperity, they need to closely cooperate and coordinate by shelving their differences and disagreements.

High hopes have been placed on China's diplomatic performance this year, as President Xi Jinping is expected to inject fresh momentum into the "major country diplomacy with Chinese characteristics".

Regardless of their geo-economic and geopolitical disparities, however, major powers should adhere to the principles of non-conflict and non-confrontation. In particular, they should jointly address outstanding global issues through effective communication and dialogue. There is enough room for cooperation among major powers when it comes to nuclear non-proliferation, reducing carbon emission and boosting global growth, which largely depends on concerted financial policies of all economies.
