Liz Truss was confirmed on Sept 5 as the new leader of the Conservative Party and the prime minister of the United Kingdom. Truss, known for her highly ideological worldview and hawkish foreign policy, replaces Boris Johnson in 10 Downing Street after he was forced out of office following a series of scandals that tarnished the reputation of his government.

Truss had secured her ascendency as part of Johnson's Cabinet, having served first as trade minister and then foreign secretary.

However, Truss' tenure as prime minister is off to an uneasy start. Things are not well in the UK. The economy is in contraction and will soon enter a formal recession. Inflation is soaring, with economists predicting that it could rise up to 23 percent by next year, and energy bills are skyrocketing as a consequence of the impact of the Russia-Ukraine conflict on energy markets.

Truss also faces the dilemma that she has been elected by only the actual members of the Conservative Party and is largely unpopular among the public in the UK. She has vowed to almost immediately take action on bringing power bills down, but aside from an immediate cap, it remains to be seen what she proposes to do to bring down prices.

However, there is another elephant in the room: China. Truss is a vocal China hawk who took every opportunity as foreign secretary to be critical of Beijing, and she enthusiastically joined the bandwagon of any US initiatives.

She replaces the more balanced and favorable approach of Johnson, who had described himself as a "Sinophile" and would have been supportive of the UK's economic engagement with China, were it not for the US.

Truss, however, has consistently and publicly sought confrontation with Beijing during her tenure as foreign secretary, with rhetoric that has been a mix of both UK chauvinism and ideological crusading.

She has pushed concepts such as a "Network of Liberty", talked about "bringing countries into the orbit of democratic, free market democracies" and argued that ideology should ultimately come first when it comes to trade.

The leadership contest with rival candidate Rishi Sunak, former chancellor of the exchequer, quickly become a "race to the bottom" in respect to China bashing, with each candidate seeking to rigorously "out-hawk "the other. This played to Truss' advantage, and as a result most commentators are pessimistic that UK-China relations will improve during her time in office. Yet, given the UK's economic reality, it would be an irrational and unwise decision to pursue a path of coldness or confrontation with China.

Truss has frequently spoken of a "global Britain" and "making Britain more competitive" for investment and business around the world. Yet it seems quite obvious that if left to her own devices, she will be confrontational toward China, which of course is detrimental to her very intentions.

After all, China is the world's second-largest economy and is one of the UK's most important trade and investment partners. According to the UK's Office of National Statistics, China was the UK's largest import partner and sixth-largest export partner for goods in 2021, with the UK having imported￡63.6 billion ($73.4 billion) of goods from China that year, while exporting ￡18.8 billion of goods. The trade between the two has increased as a direct consequence of Brexit, which has damaged the UK's ties with European markets.

In addition, 28,930 Chinese students are studying at UK universities in the 2021-22 academic year, an increase of 12 percent from the previous year. According to the British Council, this is worth￡2.55 billion a year to the British economy. It is undeniable that open, cooperative and stable economic and people-to-people ties between the two countries are highly lucrative.

Therefore, this poses the question of whether it is wise for Truss to harm ties with China further in the name of ideology, and at the behest of US-centric foreign policy goals.

If Truss is to be a successful prime minister, both at home and on the world stage, then she should be more diplomatic, prudent and rational about the UK's relations with China. Certainly, there can be no "global Britain "without considering the dynamic of the world's most populous country and largest consumer market. A foreign policy of ideological confrontation on the other hand, will be truly disastrous for the UK and will make a bad situation worse.

Before US pressure set in, UK leaders understood the value of good relations with China. This was based on reason and national interest, not ideology. Truss must avoid an abrasive relationship that would only risk isolating the UK further on the global stage.
