The Shanghai Cooperation Organization -- a six-member group led jointly by China and Russia -- will consider whether to induct Iran during a summit in Kazakhstan that begins Thursday. Membership in the group, which is focused on coordinating anti-terrorism efforts and enhancing regional connectivity, would help Tehran bolster ties with Moscow and Beijing.
The discussions come at an awkward time for President Xi Jinping, who has sought to reassure Iran's rival Saudi Arabia of China's long-standing neutrality in the regional feud. On Monday morning, four Arab nations led by Saudi Arabia severed trade and diplomatic links with Qatar, in what appeared to be punishment for maintaining ties with Iran. U.S. President Donald Trump later expressed support for the move in a tweet.
"An Iran under pressure from a U.S.-backed Saudi coalition will likely view China as an increasingly indispensable partner," said Timothy Heath, a senior international defense research analyst at RAND Corp. "There is a growing risk that the Saudi-Iranian rivalry could turn into a proxy U.S.-Chinese competition for influence in the Middle East."
Both countries are critical to Xi's efforts to expand China's clout in the region, with Saudi Arabia its second-largest source of foreign oil and Iran a key crossroads on the Belt and Road Initiative to build trade and infrastructure links across Asia. Xi elevated the countries to "comprehensive strategic partnerships" during a Middle East swing last year in which he also told the Arab League that China wasn't seeking "proxies."
Xi's tour came before Trump made Saudi Arabia the first stop on his inaugural overseas trip last month as leader, urging nations to isolate Iran for what he said was support of terrorism. The speech reasserted U.S. alliances strained by former President Barack Obama's support for the 2015 nuclear deal that granted Iran sanctions relief. China played an instrumental role in brokering the agreement, which Trump called "the worst deal ever."
So far there's been no sign that recent events have influenced China's Middle East policy. Assistant Foreign Minister Li Huilai on Monday reaffirmed the country's support for Iran upgrading its observer status with the SCO to formal membership. Xi first made the commitment during his January 2016 visit to Tehran.
In any case, Iran won't become a member immediately at the two-day summit in Astana, where Xi arrived Wednesday. The bloc refused to initiate Iran's accession last year without giving a specific reason, but China has said its membership can be put on the agenda once India and Pakistan join. Both countries, which have waited years to become members, will be added to a group that includes Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan.
Li Guofu, who overseas Middle Eastern affairs at the Foreign Ministry's China Institute of International Studies in Beijing, said China would "make maximum effort to hold up its principled position of non-interference" and attempt to "deescalate conflicts" through diplomacy.
Chinese Foreign Ministry spokesman Hua Chunying said Monday the country hoped that "relevant countries can properly resolve differences through dialogue and consultation, uphold unity and jointly promote regional peace and stability."
China may keep coming under pressure to take sides as its interests expand in the Middle East. That favors Iran, which shares overland links, a suspicion of Sunni Islamist groups and a desire to reduce American power, said Michael Singh, managing director at the Washington Institute for Near East Policy.
"It is clear that China's preference -- if forced to choose -- is for Iran," said Singh, a former regional adviser to the National Security Council. "President Trump's recent visit to Riyadh, with its over-the-top pomp and unrivaled collection of Muslim leaders, will have been a reminder to Beijing that the Arab states by and large still place their hopes in American leadership."
Still, China's relationships with both sides of the Persian Gulf divide were based on mutual interest, said Ali Vaez, a senior Iran analyst with the International Crisis Group. Saudi King Salman bin Abdulaziz returned from a March visit to Beijing with as much as $65 billion in economic and trade deals. Iran was an enthusiastic early supporter of the Belt and Road Initiative, and last month sent its finance minister to attend Xi's summit on the plan.
China's trade with Saudi Arabia amounted to $45 billion in 2016, almost double that of its commerce with Iran.
"It can neither afford to alienate them, nor is likely to be alienated by them," Vaez said. "Trade trumps all else."
