Russian President Vladimir Putin's visit to China on Saturday was brief but productive. China and Russia vowed to strengthen global strategic stability and showed support to each other on core-interest issues in joint statements.

The statements avoided mention of the US, but the problems they point out can be insinuatingly connected to it. "To strengthen global strategic stability" is a new way of speaking to remind people of the US being the biggest source of global strategic risks.

The joint statements have released outright criticism against the US, showing both Beijing and Moscow are fed up with Washington's pursuit of hegemony.

Beijing and Moscow have confirmed that their relationship is not an alliance, and it is not aimed at a third party. The affirmation is not rhetoric, but their real deliberation. A China-Russia alliance, which will bring a game-changing impact on world order, is not in the interests of either side. They are more willing to develop all-out diplomacy and maintain a normal relationship with the Western world.

However, the US' efforts to encroach on China and Russia's strategic room has rendered an interdependence between Beijing and Moscow over some core interest issues.

The US has never given up its ambitions to become a global empire. Its Prompt Global Strike system is a direct threat to any country's national security.

Forced by the US' relentless efforts to squeeze China and Russia's strategic room, Beijing and Moscow have to deal with the US back-to-back.

China and Russia have achieved agreements on principles such as opposing interference in other countries' internal affairs in the name of defending human rights, and double-standards in counterterrorism.

The Western media are fond of exaggerating any slight disagreement between China and Russia. They don't understand the resilience and openness of the Sino-Russian relationship. Neither side intends to restrict each other, and the inclusiveness adds endless vitality to Sino-Russian ties.

The US is unable to beat down the Chinese dragon and the Russian bear at the same time.

China and Russia have a lot more areas to improve their strategic cooperation, which will be further explored as the US puts more pressure on them.

Western pundits are trying to figure out whether China or Russia has the upper hand in the bilateral ties. Their theories have missed the point.

The Sino-Russian relationship is established on a highly equal footing with mutual respect. These two major powers in the world feel fulfilled instead of burdened through their strategic cooperation.

The close Sino-Russian ties are what the times require, a reflection of the trend of the world.
